Aloha, I have a gy6 50 cc moped. And I have a electricial issue. I replaced the battery, the stator, the cdi, and ect. If I leave the bike off for more than 2 days and wen I go start it the battery act like it's dead
I've been a backyard mechanic for years and considered myself somewhat knowledgeable. Never knew the stator produced AC, and the rectifier converted it to DC. Very helpful video. Thanks for posting.
I just want to say that I’m a new scooter owner which has tons of problems !! This video has single handedly taught me how to diagnose my charging system!! Great video
Just wanted to say thanks for this video. Helped me trace a faulty seat opening actuator on a Vespa GTS 300 as being the cause of a battery drain that killed the battery on a brand new bike after 1 week! Pulled fuses untik draw dropped from 250ma to 0.004 ma (I wouldn't have known a good reading without this video) then went through the things associated with that fuse. When i pulled the seat actuator it dropped to 0.004ma. Now just need to get it all done under warranty. Thanks for getting us back on the road.
omg you saved my life a little with this one. I had watched the video some time ago but just recently picked up a 50 cc buddy. It's missing the front cover - salvage auction. The fargin' rectifier was disconnected! Whether intentional or vibration I don't know but the voltage didn't drop when revving now that's it reconnected. I will be using this to deliver food as an only source of income so it's important. I had to come home yesterday as it got only to the point of kick-starting. You are the best! Now out into that 96 degree weather. lol.
Thanks Garrett, I've been having numerous problems with my scooter ( motomia 170 sport) and having watched your vids i was able to correctly diagnose and repair my baby. Thank you without your vids this would not have been possible.
Just replaced my battery and soon taking it in for an oil change. This was a great video and will allow me to have an informed conversation with the guy at the shop. Thanks very much for making this easy to follow and learn! Great tempo and visuals!
thanks brother , you helped me to understand how to use my voltmeter better too. manuals dont have real good details . fixed my bike doing exactlly what you said , only took 1.5 hrs. no issues..great job !!
Very clear and concise information especially if one is a novice. You should be an full time instructor and not just get grease under your nails. Keep going with your great instructional videos.
These are some great tips! I gotta get myself a multi meter! Ever since I had my 49cc scooter upgraded to a 100cc I've been getting all sorts of problems! I recently find myself having to constantly charge my battery every few days, so after watching this video I am convinced that there definitely must be something draining my battery while it's off.
@@Scooter_911 love your videos btw man, don't pick this comment as a hate comment because it's not intended as a hate comment :D keep up the amazing videos, it helps me with my scooter alot :D
I replaced the rectifier on my scooter it’s a big one ( rectifier ) and it still won’t recharge but everything thing else works fine ... I also have a buddy 150cc it’s a fast little monkey and it’s stock and it goes 50-52 mph kinda scary since it’s so small it kinda wobbles past 47.mph .. I got a rear flat what the size is the nut to remove rear wheel... oh’ could I put rear tire size 4.00 x 10” instead of the stock 3.50 x 10 “ it rides so low that some times I tap the oil cool thats under the battery compartment when I go up some drive ways ??
Just purchased a 2008 sage green model like you're showing us. Mine charges battery as I ride. As a Tilesetter working with the Schluter Systems Ditra Heat, we test cables with a Megohmeter
Nice explanation. Usually garage staff will not check this much deep to recognize the real problem. They usually tell to replace the battery. Even I have charged my scooter battery its not working. After watching this video I need to find out the real problem with my scooter.
This was a great video, you kept it slow enough and covered the basis enough that I can share this and your other very helpful videos to the individuals I sale scooters too as is after I've gone through them and know when I sale them they are good to go. Often times though, down the road (literally) said people will have a problem and "forget" what "as is" meant, so I text/share the appropriate self-help video that you have. I have had many motorcycles over my 55+ years alive but my first scooter is a genuine buddy 50 two stroke. Now I have two 250; '86 Honda helix & '05 cfmoto royale, 3 150cc; a Honda ruckus with a cfmoto 150 gy6 modified, an 2013 sym Wolf jet 2 classic and a Tao Tao 150 sunny, and two Tao Tao 50's one with a 100cc big bore kit and your videos have greatly helped me to repair and loan/sale scooters to persons in need of transportation while trying to get their lives back on track or while they experience a new way of life following rules and guidelines they didn't use to follow. Please keep up the good work and keep your videos coming.
Wow! Great in formation , I got a moped from China and no one wanted to touch it . But I follow all your videos . Till I found it was the the batty and my tail light . Thank you for you sharing this video .
Thanks for the video. I'm sure it will help someone. Its nice to get some in depth detail I have a suggestion for another episode. How to adjust the idle. And not "Where is the idle screw". I think we all know HOW do adjust it, but where to adjust it is the real problem. How to diagnose it when its too low, and too high, etc.
Wow that is an excellent suggestion! Coincidentally my next planned video will be a carburetor rebuild video. Maybe I will make it a 2 part series and have the second video be "how to properly adjust your carburetor"
Hi Garret! Thank you for your help with my recent battery issue. Your team went above and beyond, from picking the scooter up on time and resolved the issue the same day at below the estimated cost. I highly recommend you shop and services. Thanks again! Bryan M.
Great Videos Garrett. Particularly liked the adjustment for valves. Here are some thoughts for Future videos. Tire management - How often to replace/tread wear to stay safe, What's the difference in short case vs Long case GY6 motors, how to replace a long axle with short axle (one I am currently working on with an MZ Moskito 125R), how to replace stator, Vacuum vs Gas lines and that PITA gas valve with the vacuum line actuator, Performance Air intake system and bypass/plug vacuum lines, what else......ethanol vs Non-ethanol gas and premium vs 87 octane -ethanol wear on gaskets and fuel leak into crankcase..........replacing CCV belt.
Hi, is there a sequence for wires when you connect them from stator to the regulator/rectifier ? Does it matters where any of the 3 yellow cable enter the regulator/rectifier (also yellow) ? A "smart" dude cut the soket . TY !
Excellent question! Actually it does not matter where the stator wires enter the regulator rectifier. All of that voltage all ends up in the same place and leaving as DC on the "voltage out" wire. Throw them back where you please!
Hi so I have changed my rectifier. I also changed my my stator. It wasn't brand new it was of my original engine which I know it was working. And it's not likely to have same issue. My battery is draining when engine is on. I did stator test putting red into both connections and black to ground but again was reading 0 on AC this was the issue with both stators. Now I put the black and the red into both connections(not ground obviously but other 2) on the stator wire I get a reading of 40+ volts and 50+ when revving the engine. So am confident it's giving out enough AC to rectifier to change to DC. I have just ordered an wiring harness as this is my next thought on issue. Looking at the earth through my harness and it looks frayed and bubbled in sections..could a bad earth that causes this issue along with maybe other damaged wires that I can not see?? Sorry am not great at explaining. So I hope you understand. Love your content btw, keep it up. You make me want to tackle more and more on my bike.
I just purchased a Tao Tao Quantum Titan 150cc scooter about two weeks ago and I have similar issues. Maybe I didn't charge the battery long enough. It states to charge for up to 8 hrs., I think i charged it about that amount of time which should be good but after sitting for a day or so, it's struggling to turn over. I'll use this video to help troubleshoot if the problem persist. Thanks for posting...
On my 2011 Suzuki Burgman 650 my battery died. I replaced it and the next day drove around nearly 3hrs made a few stops and turned it on and off several times. Then it wouldn’t start up for me. Had to get a jump start. I set up my multi meter and started to see how much parasitic draw it was having it was bouncing around .24-.28ma. I started unplugging stuff and seeing what had an effect.... nothing until the instrument cluster, I unplugged the cluster and it dropped to .01ma. I’m going to pull the cluster apart and see if anything is damaged.
I'm having a bit of trouble understanding. I backprobed the regulator/rectifier as described at 6:28 and the voltage barely increased when I revved the engine. I checked for continuity between the ground wire on the regulator/rectifier and the negative terminal on the battery, and there's continuity. Everything else seems to check out. Does this mean my regulator/rectifier is bad? I have a 2009 Kymco Super8 150.
There is a good possibility you do! But when checking the ground side, measure resistance instead of continuity. You want to make sure you have less than 3 ohms resistance and continuity can be deceiving that way. Also make sure your stator output is decent before condemning your regulator rectifier. Good luck!
@@Scooter_911 I'll check again in the morning but if I remember correctly my multimeter said the resistance was less than 1 ohm. Also, the stator wires were giving me 40V AC when I revved. Thanks so much for your help!!
@@Scooter_911 Okay I just checked resistance between the ground wire on the reg/rec and the negative terminal on the battery. With the scooter turned off I get 0.1Ω. When I power it on that jumps to 3.3kΩ. However starting the engine and revving takes it back down to 0Ω. Thanks again for all your help!
There is a lot of confusion and misinformation about clutch spring rates and variator roller weights if you have the time please touch on that in a video it would be greatly appreciated love your style thank you very much.
The ignition switch on the 170i is very particular and has some small circuit built into the back of it. The regular buddy 125/150 switch bolts right up and plugs in but the bike will not run. Other than that make sure you have good power and connection to the ECM (engine control unit) and check all of your fuses!
I love your fitst couple of episodes. Not problems I'm currently having but enlightening(no pun intended) nonetheless. I'd like to hear a simple description of the main functional differences between a Vespa, which I think we all wish we were driving, and the cheap chinese one I'm actually driving. So far the lessons seem universal(props on that) but I'd be interested in knowing when you get into engine/exhaust/component systems how much variation to expect or if they maintain a certain standard of quality control that means I can apply what I learn to my ride just that easy. Keep up the good work.
That's a really interesting idea! It would be really neat to do the LX150 against that LX150 clone! Or even an old PX against one of the Indian PX clones like the Bajaj or the Stella!
In the portion of the video where you check the stator AC voltage did you start the scooter while the multimeter was connected to the stator-side pins? And do you have to start the scooter again every time you want to check a new pin?
Yes I did! The engine needs to be running for the stator to be generating electricity. You do not have to shut engine down every time you want to check a different leg of the stator but it needs to be running when you check it. I hope that helps!
@@Scooter_911 So i started working on my own scooter after seeing this video and it seems like my AC voltage is good on the stator side pins (i had some trouble with this cuz my multimeter is different then yours it has a 200 and 600 setting and on the 600 setting it looked good) and the voltage coming out of my regulator/rectifier was around 13.8-14v, but my battery on its own never got above 12.1v like you showed at the beginning as an example of a bad charging system. Im not sure what to make of the results. The stator wires on the regulator/rectifier also had absurdly low voltage compared to the stator-side pins. Any idea whats going on? Am i doing something wrong? Thanks!
@@Korterra1364 nice work! I've seen that exact symptom a lot and it sounds like you have it nailed down! What's most likely happening is you have excessive resistance in the charge wire (from the regulator rectifier to the battery). This is usually do to damage somewhere deep inside the wire harness. The easiest fix for that is called an "overlay". You basically cut that wire right after the regulator and lay down a new wire tying it in to the harness or connecting it directly to the battery terminal. I should mention before you do this make sure you're battery is in good shape as a bad battery can mimic your symptom. You can also ohm the wire from the reg connector to the battery terminal. You should have less than 1 ohm resistance. Good luck and let me know what you find!
@@Scooter_911 Interesting update. I found the frayed wire and got some connectors and heatshrink from Lowes and cut, stripped, and connected the two ends. Now my regulator/rectifier voltage on the red wire is barely peaking over 13v and the battery isnt budging past idle voltage either. Is it possible my reg/rec AND battery are both bad? Would checking resistance help narrow this down? If so, I should connect check the resistance from the red reg/rec wire to the positive battery terminal while the scooter is running? I've checked the resistance across just the red wire with nothing running and that was 0.1-0.3 ohms, would that confirm the wire is in good shape? Thanks for all your help.
@@Korterra1364 wow excellent work! Have you considered a career as a technician?!? No, the scooter does not have to be running in order to check the resistance of the charge wire. Did you also check to see if that wire has any resistance to ground (once you have unplugged it from the reg/rec). It is possible that wire has been shorted to ground and so the full current is not being conducted to the battery. If there is no continuity to ground then I would imagine your reg/rec has been damaged by the short, and it might need replacing. The thing you can do is called a "wire overlay". Basically, disconnect the suspect charge wire and connect a new good wire from the reg/rec charge pin directly to the battery and see what you get. You are doing excellent work keep it up! And keep me posted!
Nice video, thanks. And am happy to see a corner front of my Favorite car , Ford Pinto. I know that everybody blame the Pinto, but my experience was 10 years with no problems, only simple maintenance. And I was avoiding to purchase it from a Friend. Thanks again.
Thks four your excellent video I have a Piaggio Zip 2T other day I drive and same one stop me and tell me my rear lights is blinking after 2 days all my lights is blown front and rear I’m surprise my fuse don’t blown also when I drive in full throttle same times is cut don’t the speed what you think is my regulator fault thank you help appreciate
did the electrical diagnoses as you exclaimed in the above clip, everything checks out, no parasitic drain. Noticed the carburator is flooded and keeps on flooding. I removed and cleaned the carburator a while back and adjusted the enrichment screw. Need help, there is spark and the stator motor turns but it struggles to ignite. please ineed advise
Thanks for the lovely video I did my check on the parasite drain check and it's showing 0.021 on my meter is it ok as I have digital speedometer n tachometer with clock on my bike.
Hi. Great channel with lots of useful tips. Thank you for sharing. The only suggestion so far is to keep the sound effects at a lower volume than your voice. I had to go over some portions a few times to understand what you were saying.
Garret help! besides other problems I had with my Yamaha Zuma 50 (2004) now I've learned that the battery dies super fast even after being charged (dont own a charger myself, took it to my local autoparts store) so the electric start will not work. Example: I had it charged, connected it, horn worked fine. Tried electric start and made that "wah wah" sound you talked about and scooter wouldnt start (it only starts with the kickstart which thanks to you I've learned today that you shouldnt use it everyday) and then right after the horn wouldnt even work, just clicks, test it with my $10 multimeter and it reads less than 10v. How could it die in a matter of minutes or seconds even? I bought that battery on December 2019. Also checked the battery while running and it was about 7 or 9v (not 13 or 14 like you said if the stator is working fine). Hope you read this :( thank you and I love your videos bro you one of the best TH-camrs in my opinion.
Thanks as this was helpful. If this battery was to be a 100amph 12V battery and the system in question drains the battery very quickly, what sort of rectifier would be used to recharge the battery as quickly as drained. 🤷🏾♂️ Some say rectifiers can't recharge 100 amp batteries and above. Any help?
I've also had a drain issue with my previous battery and considering this new one was dead after my most recent starting issues, I'll watch this & see if it can help resolve that. Where's the spark plugs at on a TaoTao Pony 50, what sockets & fittings am I going to need for this? I know it uses an M8, M10 & M12 for things like the oil / gear oil, etc....
The sparkplug is located on the right side of the cylinder head. Remove the front inspection cover (by where your heels are when you are riding) and you'll find it there.
I have a Jonway yy250t aka Roketa 54 250, it has a parasitic drain but cannot find the source and I am thinking it might be the alarm system. Is there a way to check the alarm preferably without taking the fairing off?
thank you for your video. A question for you about the battery and the multimeter. I have an old kymco r16 50cc 4t (2009 year) , i think that it's a GY6 motor carburetor system. I've checked the battery with my multimeter and the value is about 12.70.... when i rev up , when i increase the rpm , the multimeter gives me a value about 16.80.... is it too high? Maybe do i have to change the regulator/rectifier? Sometimes i have problems to start my scooter... my battery was off and i recharged it using a charger....
also, i don't know what "backprobe" means. and where does the other probe on my multi-meter go? (the one that doesn't touch the battery wire that the rectifier connects to) thanks jeff
Great video! Hope you can help on this issue: A few days ago, while riding my SYM VS 125, a lot of smoke started coming out of the front of the bike and the engine started to fail. I turned off the ignition and cut the battery current. At home I took it apart to see what was going on and the rectifier was visibly burnt. I took the bike to a workshop where they changed the rectifier and the battery, but they didn't solve the problem. The new rectifier continues to heat up a lot and too fast, as if something is short circuiting. As they couldn't solve the problem and it still cost me a few €€, I picked up the motorcycle with the fault. Tests i have done: - the battery is new and has 13.1V before the starter - with the three yellow wires from the stator connected to the rectifier, the bike works fine at low revs, fails at medium and the rectifier heats up uncontrollably; with these wires disconnected from the rectifier, the bike works well at any speed, but as we know, the battery is not charged - at idle the 3 yellow wires measure about 40V from stator - the resistant test on stator show equal values on three wires; no ground conductivity; no open circuit on each coil - apparently all the masses are well connected. Any idea what it could be causing this recurrent failure of the rectifier? Note: traditional G6Y carburetor engine with electronic rectifier and CDI, year 2010.
On batery there are two data: voltage and amper/hour. You talk a lot about voltage, and nothing about amperage.what is amount od amperage that regler send to accu?..thank you for reply.
thank you for the video, very informative. i have a tomos 150cc nitro and when been fighting it battery drain for a while. So today checked the voltage without a battery installed at the battery leads and its 7-9v when rev'd...i would expect the 14v there. Now once i find the issue stator or regulator, would you know if a stator and regulator would work from a 50cc model? i cannot track down 150cc parts for this. cheers!
its best to just identify the parts visually and find replacements. chinese scooters often are made with whatever parts are available that day. I've seen 2 of the same year make and model scooters uncrated with different parts. hope that helps. Good luck!
@@Scooter_911 thanks again for the info. I metered the stator wires while plugged into the wire harness and got 12v and 20v +/- 2 V when reved, then unplugged from the harness it went from 20v to 50v revd. I'm assuming the difference is the system us under load? I got another regulator from a 50cc (it was the same) and now getting 10-11v rev'd, but still not enough to keep the battery charged. Would you think swapping the stator from the 50cc would be worth the effort? I don't have a flywheel pully but can borrow hardware store 2-prong pully. Any other areas of the scooter to consider? thank you
@@mikec376 you're absolutely right, the readings will definitely vary due to the load of the charging system. Did you check all 3 legs of the stator? Yes if the 50cc stator is identical it's worth a shot. Check out this video I made on replacing stators here th-cam.com/video/pPkbJ0FB3dM/w-d-xo.html
My scooter could not keep up with a radio and running light i installed. So did the ac voltage check and either the yellow or white wire i can't remember which one was charging 30ac volts and up when revved and the other one was way lower I think I teens to 20's. So I have ordered 2 more 8 pole stators like the one in it already. They all check out the same. I could not believe they were all bad. I ordered a 11 pole update stator and it has 3 yellow output wires. Upon checking them 2 of them are putting out 30v and up however the 3rd one is low just like the 8 pole stator. This is driving me crazy. Some people say all the wires should put out at least 40 volts and up when revved. Others have said anything over 12volts is good confused.
So I'm getting spark and fuel I adjusted the valves at 14 on the intake and 15 on the exhaust only thing I don't have is the compression tester and I can't get this moped to start I'm ready to pull my hair out 911.. any encouraging thoughts or direction you could give me would be so freaking thankful I appreciate it and I like your shows keep it up I'm learning things though and I appreciate your time.
Hello Sir I got 50cc sym scooter. Last week while driving the scooter sounds different than normal sounds and in few minute the scooter went off and didn't start. Do you think what could have happened.
Thats tough, it could be a lot of things. But I made a video to try to help you find out why it won't start! th-cam.com/video/xW5y7a7CB1c/w-d-xo.html Good luck friend!
Honestly there really is no benefit to a lithium battery in a scooter. And they are more finicky to maintain. Its actually not good for them to be charged by the scooter's charging system like a regular battery.
Buddy, I just discovered your videos. You are awesome. The info, super helpful, your sense of humor... on point! Your ending statement "Bucket of bolts and people who work on them are not smarter than you...." GENIUS! and the outtakes to show that effort goes into the videos to get it right. Not to mention "the editing" - The hell behind the scenes that viewers don't see or understand how much time goes into it. If you read this far... Cheers. Just a big high five bro!!!
Ok, I am new to this but your videos are helping me to diagnose our scooter. There is power but it won't turn over. It will run for a day and then stop. Did a valve adjustment and it worked then the next morning it wouldn't start. It just will not turn over the engine. Cleaned the carb and air filter, new spark plug and it originally had a crappy way too high voltage additional light on the front which we removed. We figured it was draining the battery. But, put a brand new battery in this morning and it will crank but not turn over. Any suggestions?
my scooty had broken starter magnet inside didnt turn the rotor properly then stuck at some point , then the relay done some cracking sound and my battery was dieing when tried for too long, i searched for a scooter startor in moto shop but for my surprise was auto stator , find it in new shop , hope it will start when i put the new one , its a Suzuki 150 cc epicuro model
I know this video is old . But i bought a used scooter this past weekend as a proyect scooter for winter.. charging systen is bad voltage jumps non stop . 8 volts to 15 volts . Non stop . . So i ordered new stator and regulator. Still does the same thing. .. maybe is the flywheel ? Magnet ?
Thanks for this vid very informative. I have a Peugeot Looxor 125 and has a problem with charging. Checked voltage giving 14.5v but on lights on 13.5v rev engine. On stator there are 5 pinouts. When checked resistance to earth giving me 115 ohms on one and the others all different. Any help please? Thks.
Hey Garret ! Thanks for the video ! Good knowledge I just put fresh battery in my scooter its a 1986 Honda elite 150d. As I push the start button the headlight goes out and the turning lights light up more trys tarting clicks some. Although when it does start it dies soon after.
Hello. First thank you for the info in the video. I wanted to ask you a question. I have a 2007 honda sh150i and when i measure the battery it reads about 12 to max 13 volts when ideling and 15 to 15.3 when turning the throtle near the max. Is that correct in the high rpm or does it have a bad voltage regulator? Thank you.
Please help!!! I have low voltage at the battery, and it drains it. I measured voltage at the stator, like you did in the middle of the video. When its unplugged voltage is good, about 45v (+/-) but when plugged in, it drops to about 4-5v same at the voltage regulator. I get same voltage at the battery, regardless of engine RPM
@@Scooter_911 I have a new rectifier and new stator.. if I unplug rectifier and tone pins, they are all somehow, somewhere connected to ground.. how where could they be connected to ground? Is this even the right way of testing?
My battery keeps showing voltage from 11.5 to 16.8 V when active. The volts change every 30 seconds to anything in that range. Also when fully charged it can still struggle to start but even after a long drive when I stop the engine and start up, it struggles again. I bought a new rectifier and I am having the same issue. Could an exhausted or defect battery be causing my rectifier to keep sending in fluctuating volts as its trying to keep the battery charged?
Thanks for your reply I appreciate it. Problem here on the West Coast California it’s hard to get parts for kymco -the dealers are all complaining and most are droppin the brand
Having a starting issue, the bike turns over but does not start. When I kick start it does the same thing. I have a dong fang 50cc scooter. I have replaced the battery, cdi, ignition coil, and spark plug. It just keeps making the same noise.
So my ground wire from my stator is reading less than like 7 acv while revving the other two seem good is there a way to just fix the ground wire dose it mean it's improperly grounded or something I tried installing two knew stators but the scooter wouldn't start with either of them so I put the old one back on .. mostly just wondering if it's a grounding issue and if so how to fix it if the green is indeed a ground .. or if you know why a knew stator would cause it to not start at all installed same way brand knew same kind of stator ??? Thank you to whoever can answer this knowing what they are talking about ...
Hi thk fr the nice video when charging the battery scooter i can drive whole day but leave overnight scooter wont start unless i charging it again the stator is new cdi n ignition coil solenoid r ok does it means that the battery is not good
I have a Peugeot Speedfight 4 scooter. When the engine is off, a current of 12 mA is drawn from the battery at regular 2-second intervals. Is this a fault? Could this current be drawn by the immobilizer or ECU system? As a result, the battery becomes unable to start the engine after a week of inactivity.
Hello, i have a Yamaha aerox 50cc and i get 10volts ac out of the stator wire 1 and 18volts out of the stator wire 2.Normally both wires go to the rectifier.When i give trottle it only get a little bit higher...10volts to 12volts and that 18volts to 19-20volts. Is this normal ?
Got a yamahaTW200 with such symptom, could you explain how the steps would be modified on a motorcycle? I watched many videos on this issue, really appreciate how orderly you explain things. Thank you!
hi. i change on my 49cc 4T new flywheel, stator, rectifier. obtain 13,3v to 15v but when turn on light voltage drop down even accelerate. please help! thanks
I'm a certified motorcycle technician and this video was better than the training I paid mucho bucks for! Good job.
Hey dude, the bloopers at the end of the video was very funny. The instruction was excellent to outstanding.
😊😊😊
Aloha, I have a gy6 50 cc moped. And I have a electricial issue. I replaced the battery, the stator, the cdi, and ect. If I leave the bike off for more than 2 days and wen I go start it the battery act like it's dead
This is by far the clearest and easiest video on GY6 electrical system I have seen. Top job!
I've been a backyard mechanic for years and considered myself somewhat knowledgeable. Never knew the stator produced AC, and the rectifier converted it to DC. Very helpful video. Thanks for posting.
Compared to my many years of watching clips from others........You fully earned the accolades!
Faaaaacctttsss
You are the ChrisFix of scooters. Straight forward. No bs sponsor stuff. Hats off to you brother.
I just want to say that I’m a new scooter owner which has tons of problems !! This video has single handedly taught me how to diagnose my charging system!! Great video
So glad to hear it!
Thanks so much 👍🏽
Your step by step training is for sure the best teaching yet.
Just wanted to say thanks for this video. Helped me trace a faulty seat opening actuator on a Vespa GTS 300 as being the cause of a battery drain that killed the battery on a brand new bike after 1 week! Pulled fuses untik draw dropped from 250ma to 0.004 ma (I wouldn't have known a good reading without this video) then went through the things associated with that fuse. When i pulled the seat actuator it dropped to 0.004ma. Now just need to get it all done under warranty. Thanks for getting us back on the road.
omg you saved my life a little with this one.
I had watched the video some time ago but just recently picked up a 50 cc buddy.
It's missing the front cover - salvage auction.
The fargin' rectifier was disconnected!
Whether intentional or vibration I don't know but the voltage didn't drop when revving now that's it reconnected.
I will be using this to deliver food as an only source of income so it's important.
I had to come home yesterday as it got only to the point of kick-starting.
You are the best!
Now out into that 96 degree weather. lol.
What a great feeling it is learning this stuff from you,
Really appreciate your hard work!
Literally just finishing fixing my scooter for a 1/10th the price of taking it to the garage thanks to you. You're a star! thanks bro
make it looks like a 90s sitcom while explaining technical stuff and makes them easy.
THX DUDE !
You are the Mr. Rogers of scooters and it makes me so happy.
Thank you on levels of gratitude I cant even begin to express.
Those are some kind words neighbor. Glad to help!
Round of applause. Amazing. Outstanding quality. I fully appreciate your time and effort!
😁👍
Thank you so much! Glad you liked it and I hope it helped you!
Thanks Garrett, I've been having numerous problems with my scooter ( motomia 170 sport) and having watched your vids i was able to correctly diagnose and repair my baby. Thank you without your vids this would not have been possible.
So glad to hear it my friend! Keep it shiny-side up!
Just replaced my battery and soon taking it in for an oil change. This was a great video and will allow me to have an informed conversation with the guy at the shop. Thanks very much for making this easy to follow and learn! Great tempo and visuals!
thanks brother , you helped me to understand how to use my voltmeter better too. manuals dont have real good details . fixed my bike doing exactlly what you said , only took 1.5 hrs. no issues..great job !!
Nice work!
Very clear and concise information especially if one is a novice. You should be an full time instructor and not just get grease under your nails. Keep going with your great instructional videos.
Wow, those are kind words. Thanks Doug, there are more to come!
These are some great tips! I gotta get myself a multi meter! Ever since I had my 49cc scooter upgraded to a 100cc I've been getting all sorts of problems! I recently find myself having to constantly charge my battery every few days, so after watching this video I am convinced that there definitely must be something draining my battery while it's off.
Wow! I'm so glad I could shed some light on the subject! Let me know how the diagnosing goes! I'll be here if you have any further questions.
How many sound effects do you want?
Garret: YES
Hahahaha that made my morning

I replaced the rectifier on my scooter it’s a big one ( rectifier ) and it still won’t recharge but everything thing else works fine ... I also have a buddy 150cc it’s a fast little monkey and it’s stock and it goes 50-52 mph kinda scary since it’s so small it kinda wobbles past 47.mph .. I got a rear flat what the size is the nut to remove rear wheel... oh’ could I put rear tire size 4.00 x 10” instead of the stock 3.50 x 10 “ it rides so low that some times I tap the oil cool thats under the battery compartment when I go up some drive ways ??
I got the exact same tool box (box on the left) knew I could trust the video instantly. I wonder what year the box was made ive had it my whole life.
The best videos on the TH-cam. This man has saves me a lot of money and time and has taught me a ton.
This video was very enLIGHTening
Booo, go home
Just purchased a 2008 sage green model like you're showing us. Mine charges battery as I ride. As a Tilesetter working with the Schluter Systems Ditra Heat, we test cables with a Megohmeter
Nice explanation. Usually garage staff will not check this much deep to recognize the real problem. They usually tell to replace the battery. Even I have charged my scooter battery its not working. After watching this video I need to find out the real problem with my scooter.
So glad to hear it! Hope you figure it out!
This was a great video, you kept it slow enough and covered the basis enough that I can share this and your other very helpful videos to the individuals I sale scooters too as is after I've gone through them and know when I sale them they are good to go. Often times though, down the road (literally) said people will have a problem and "forget" what "as is" meant, so I text/share the appropriate self-help video that you have.
I have had many motorcycles over my 55+ years alive but my first scooter is a
genuine buddy 50 two stroke. Now I have two 250; '86 Honda helix & '05 cfmoto royale, 3 150cc; a Honda ruckus with a cfmoto 150 gy6 modified, an 2013 sym Wolf jet 2 classic and a Tao Tao 150 sunny, and two Tao Tao 50's one with a 100cc big bore kit and your videos have greatly helped me to repair and loan/sale scooters to persons in need of transportation while trying to get their lives back on track or while they experience a new way of life following rules and guidelines they didn't use to follow. Please keep up the good work and keep your videos coming.
Wow thank you very much for that comment and thank you even more for sharing my videos with your customers!
Wow! Great in formation , I got a moped from China and no one wanted to touch it . But I follow all your videos . Till I found it was the the batty and my tail light . Thank you for you sharing this video .
I really like how you test the stator without pulling it first.
Without you I would be so lost right now- thanks for all you've done to educate us!!
Thanks for the video. I'm sure it will help someone. Its nice to get some in depth detail
I have a suggestion for another episode. How to adjust the idle. And not "Where is the idle screw". I think we all know HOW do adjust it, but where to adjust it is the real problem. How to diagnose it when its too low, and too high, etc.
Wow that is an excellent suggestion! Coincidentally my next planned video will be a carburetor rebuild video. Maybe I will make it a 2 part series and have the second video be "how to properly adjust your carburetor"
Great video ... short, simple and to the point. Like the sound effects, they help keep my attention.
Hi Garret! Thank you for your help with my recent battery issue. Your team went above and beyond, from picking the scooter up on time and resolved the issue the same day at below the estimated cost. I highly recommend you shop and services. Thanks again! Bryan M.
doing homework for future project coming up. You get an "A" Thank you very much! will review again.
Thank you for doing this video. Your video has more informative than most out there. Keep up the good work man.
Thanks dude! More to come!
Great Videos Garrett. Particularly liked the adjustment for valves. Here are some thoughts for Future videos. Tire management - How often to replace/tread wear to stay safe, What's the difference in short case vs Long case GY6 motors, how to replace a long axle with short axle (one I am currently working on with an MZ Moskito 125R), how to replace stator, Vacuum vs Gas lines and that PITA gas valve with the vacuum line actuator, Performance Air intake system and bypass/plug vacuum lines, what else......ethanol vs Non-ethanol gas and premium vs 87 octane -ethanol wear on gaskets and fuel leak into crankcase..........replacing CCV belt.
Hi, is there a sequence for wires when you connect them from stator to the regulator/rectifier
? Does it matters where any of the 3 yellow cable enter the regulator/rectifier (also yellow) ? A "smart" dude cut the soket . TY !
Excellent question! Actually it does not matter where the stator wires enter the regulator rectifier. All of that voltage all ends up in the same place and leaving as DC on the "voltage out" wire. Throw them back where you please!
@@Scooter_911 Thank you!
Hi so I have changed my rectifier. I also changed my my stator. It wasn't brand new it was of my original engine which I know it was working. And it's not likely to have same issue. My battery is draining when engine is on. I did stator test putting red into both connections and black to ground but again was reading 0 on AC this was the issue with both stators. Now I put the black and the red into both connections(not ground obviously but other 2) on the stator wire I get a reading of 40+ volts and 50+ when revving the engine. So am confident it's giving out enough AC to rectifier to change to DC. I have just ordered an wiring harness as this is my next thought on issue. Looking at the earth through my harness and it looks frayed and bubbled in sections..could a bad earth that causes this issue along with maybe other damaged wires that I can not see?? Sorry am not great at explaining. So I hope you understand. Love your content btw, keep it up. You make me want to tackle more and more on my bike.
GREAT JOB ! YOU FOR SURE NOT WHAT YOU DOING, I learn alot from you now don't know the CHARGE of it but it did help me , thanks Kimm
Thank you so much! And nice pun!
Best video on the topic i have ever seen.
@@hansmarheim7620 that is very kind! Thank you very much!
I just purchased a Tao Tao Quantum Titan 150cc scooter about two weeks ago and I have similar issues. Maybe I didn't charge the battery long enough. It states to charge for up to 8 hrs., I think i charged it about that amount of time which should be good but after sitting for a day or so, it's struggling to turn over. I'll use this video to help troubleshoot if the problem persist. Thanks for posting...
On my 2011 Suzuki Burgman 650 my battery died. I replaced it and the next day drove around nearly 3hrs made a few stops and turned it on and off several times. Then it wouldn’t start up for me. Had to get a jump start. I set up my multi meter and started to see how much parasitic draw it was having it was bouncing around .24-.28ma. I started unplugging stuff and seeing what had an effect.... nothing until the instrument cluster, I unplugged the cluster and it dropped to .01ma. I’m going to pull the cluster apart and see if anything is damaged.
I'm having a bit of trouble understanding. I backprobed the regulator/rectifier as described at 6:28 and the voltage barely increased when I revved the engine. I checked for continuity between the ground wire on the regulator/rectifier and the negative terminal on the battery, and there's continuity. Everything else seems to check out. Does this mean my regulator/rectifier is bad? I have a 2009 Kymco Super8 150.
There is a good possibility you do! But when checking the ground side, measure resistance instead of continuity. You want to make sure you have less than 3 ohms resistance and continuity can be deceiving that way. Also make sure your stator output is decent before condemning your regulator rectifier. Good luck!
@@Scooter_911 I'll check again in the morning but if I remember correctly my multimeter said the resistance was less than 1 ohm. Also, the stator wires were giving me 40V AC when I revved.
Thanks so much for your help!!
@@Muniosi nice work! yep that sounds like you need a reg/rec
@@Scooter_911 Okay I just checked resistance between the ground wire on the reg/rec and the negative terminal on the battery. With the scooter turned off I get 0.1Ω. When I power it on that jumps to 3.3kΩ. However starting the engine and revving takes it back down to 0Ω.
Thanks again for all your help!
Thanks for your great explanation. Do you also have a video on how to work if you have no power at all. I could really use that now.
There is a lot of confusion and misinformation about clutch spring rates and variator roller weights if you have the time please touch on that in a video it would be greatly appreciated love your style thank you very much.
Wow that's an excellent idea!
Sym stators are grounded on all three windings and have chassis resistors also
I have a question I cant seem to find the answer for. I have a 2012 Genuine Buddy 170i. I have no spark and no fuel. What would control both of those?
The ignition switch on the 170i is very particular and has some small circuit built into the back of it. The regular buddy 125/150 switch bolts right up and plugs in but the bike will not run. Other than that make sure you have good power and connection to the ECM (engine control unit) and check all of your fuses!
@@Scooter_911 You saved me a lot of headache. Exactly what it was. Well another 2012 170i back on the road!
@@BrownStripeyCat nice work my friend! Keep it shiny-side up?
I love your fitst couple of episodes. Not problems I'm currently having but enlightening(no pun intended) nonetheless. I'd like to hear a simple description of the main functional differences between a Vespa, which I think we all wish we were driving, and the cheap chinese one I'm actually driving. So far the lessons seem universal(props on that) but I'd be interested in knowing when you get into engine/exhaust/component systems how much variation to expect or if they maintain a certain standard of quality control that means I can apply what I learn to my ride just that easy. Keep up the good work.
That's a really interesting idea! It would be really neat to do the LX150 against that LX150 clone! Or even an old PX against one of the Indian PX clones like the Bajaj or the Stella!
In the portion of the video where you check the stator AC voltage did you start the scooter while the multimeter was connected to the stator-side pins? And do you have to start the scooter again every time you want to check a new pin?
Yes I did! The engine needs to be running for the stator to be generating electricity. You do not have to shut engine down every time you want to check a different leg of the stator but it needs to be running when you check it. I hope that helps!
@@Scooter_911 So i started working on my own scooter after seeing this video and it seems like my AC voltage is good on the stator side pins (i had some trouble with this cuz my multimeter is different then yours it has a 200 and 600 setting and on the 600 setting it looked good) and the voltage coming out of my regulator/rectifier was around 13.8-14v, but my battery on its own never got above 12.1v like you showed at the beginning as an example of a bad charging system. Im not sure what to make of the results. The stator wires on the regulator/rectifier also had absurdly low voltage compared to the stator-side pins. Any idea whats going on? Am i doing something wrong?
Thanks!
@@Korterra1364 nice work! I've seen that exact symptom a lot and it sounds like you have it nailed down! What's most likely happening is you have excessive resistance in the charge wire (from the regulator rectifier to the battery). This is usually do to damage somewhere deep inside the wire harness. The easiest fix for that is called an "overlay". You basically cut that wire right after the regulator and lay down a new wire tying it in to the harness or connecting it directly to the battery terminal. I should mention before you do this make sure you're battery is in good shape as a bad battery can mimic your symptom. You can also ohm the wire from the reg connector to the battery terminal. You should have less than 1 ohm resistance. Good luck and let me know what you find!
@@Scooter_911 Interesting update. I found the frayed wire and got some connectors and heatshrink from Lowes and cut, stripped, and connected the two ends. Now my regulator/rectifier voltage on the red wire is barely peaking over 13v and the battery isnt budging past idle voltage either. Is it possible my reg/rec AND battery are both bad? Would checking resistance help narrow this down? If so, I should connect check the resistance from the red reg/rec wire to the positive battery terminal while the scooter is running? I've checked the resistance across just the red wire with nothing running and that was 0.1-0.3 ohms, would that confirm the wire is in good shape? Thanks for all your help.
@@Korterra1364 wow excellent work! Have you considered a career as a technician?!? No, the scooter does not have to be running in order to check the resistance of the charge wire. Did you also check to see if that wire has any resistance to ground (once you have unplugged it from the reg/rec). It is possible that wire has been shorted to ground and so the full current is not being conducted to the battery. If there is no continuity to ground then I would imagine your reg/rec has been damaged by the short, and it might need replacing. The thing you can do is called a "wire overlay". Basically, disconnect the suspect charge wire and connect a new good wire from the reg/rec charge pin directly to the battery and see what you get. You are doing excellent work keep it up! And keep me posted!
Nice video, thanks. And am happy to see a corner front of my Favorite car , Ford Pinto. I know that everybody blame the Pinto, but my experience was 10 years with no problems, only simple maintenance. And I was avoiding to purchase it from a Friend. Thanks again.

You're explanation is very clear, anyone can understand thanks for sharing
did the electrical diagnoses as you exclaimed in the above clip, everything checks out, no parasitic drain. Noticed the carburator is flooded and keeps on flooding. I removed and cleaned the carburator a while back and adjusted the enrichment screw. Need help, there is spark and the stator motor turns but it struggles to ignite. please ineed advise
Thanks for the lovely video I did my check on the parasite drain check and it's showing 0.021 on my meter is it ok as I have digital speedometer n tachometer with clock on my bike.
winding is new, rr. is new wiring was tested and still getting 12v. fail could be a low magnet effect?
I haven't seen many magnets go bad. You might have a ground issue or possibly excess resistance in the harness
:) 12 volts at idle you say huh. Mine has 2 volts at idle, and when I rev it up it goes below 1 volt. Good video keep the good up the work
Hi. Great channel with lots of useful tips. Thank you for sharing. The only suggestion so far is to keep the sound effects at a lower volume than your voice. I had to go over some portions a few times to understand what you were saying.
Garret help! besides other problems I had with my Yamaha Zuma 50 (2004) now I've learned that the battery dies super fast even after being charged (dont own a charger myself, took it to my local autoparts store) so the electric start will not work. Example: I had it charged, connected it, horn worked fine. Tried electric start and made that "wah wah" sound you talked about and scooter wouldnt start (it only starts with the kickstart which thanks to you I've learned today that you shouldnt use it everyday) and then right after the horn wouldnt even work, just clicks, test it with my $10 multimeter and it reads less than 10v. How could it die in a matter of minutes or seconds even? I bought that battery on December 2019. Also checked the battery while running and it was about 7 or 9v (not 13 or 14 like you said if the stator is working fine). Hope you read this :( thank you and I love your videos bro you one of the best TH-camrs in my opinion.
Sounds like you might have both a bad battery AND a parasitic drain. Good thing you have that multimeter! You're going to need to use it!
@@Scooter_911 but the battery is practically new man how could this had happened T.T
The way you explained this was amazing thanks!
Would you work on my DF50sst? Nobody else will
You really simplify how to work on my scooter
Thanks as this was helpful. If this battery was to be a 100amph 12V battery and the system in question drains the battery very quickly, what sort of rectifier would be used to recharge the battery as quickly as drained. 🤷🏾♂️ Some say rectifiers can't recharge 100 amp batteries and above. Any help?
Holy crap!
Do you do other vids lol!
Best DIY how to video ive ever seen.
Definitely earned my subscription 🙌
I've also had a drain issue with my previous battery and considering this new one was dead after my most recent starting issues, I'll watch this & see if it can help resolve that. Where's the spark plugs at on a TaoTao Pony 50, what sockets & fittings am I going to need for this? I know it uses an M8, M10 & M12 for things like the oil / gear oil, etc....
The sparkplug is located on the right side of the cylinder head. Remove the front inspection cover (by where your heels are when you are riding) and you'll find it there.
Is this the correct Regulator Rectifier for a Pony 50?

I have a Jonway yy250t aka Roketa 54 250, it has a parasitic drain but cannot find the source and I am thinking it might be the alarm system. Is there a way to check the alarm preferably without taking the fairing off?
unfortunately not. You'll have to disconnect the alarm to see if its the source of your drain.
@@Scooter_911 I had a 2.5amp drain and the moment I unplugged the alarm system the drain disappeared. I guess I am now buying a new alarm system.

@@Scooter_911 You make the diagnostic of these issues super simple. I am happy that I decided to follow you.
thank you for your video. A question for you about the battery and the multimeter. I have an old kymco r16 50cc 4t (2009 year) , i think that it's a GY6 motor carburetor system. I've checked the battery with my multimeter and the value is about 12.70.... when i rev up , when i increase the rpm , the multimeter gives me a value about 16.80.... is it too high? Maybe do i have to change the regulator/rectifier? Sometimes i have problems to start my scooter... my battery was off and i recharged it using a charger....
also, i don't know what "backprobe" means. and where does the other probe on my multi-meter go? (the one that doesn't touch the battery wire that the rectifier connects to) thanks jeff
Great video!
Hope you can help on this issue:
A few days ago, while riding my SYM VS 125, a lot of smoke started coming out of the front of the bike and the engine started to fail. I turned off the ignition and cut the battery current.
At home I took it apart to see what was going on and the rectifier was visibly burnt.
I took the bike to a workshop where they changed the rectifier and the battery, but they didn't solve the problem. The new rectifier continues to heat up a lot and too fast, as if something is short circuiting.
As they couldn't solve the problem and it still cost me a few €€, I picked up the motorcycle with the fault.
Tests i have done:
- the battery is new and has 13.1V before the starter
- with the three yellow wires from the stator connected to the rectifier, the bike works fine at low revs, fails at medium and the rectifier heats up uncontrollably; with these wires disconnected from the rectifier, the bike works well at any speed, but as we know, the battery is not charged
- at idle the 3 yellow wires measure about 40V from stator
- the resistant test on stator show equal values on three wires; no ground conductivity; no open circuit on each coil
- apparently all the masses are well connected.
Any idea what it could be causing this recurrent failure of the rectifier?
Note: traditional G6Y carburetor engine with electronic rectifier and CDI, year 2010.
I can't get enough of you videos thank you I am learning a lot
Man,yours techings are awesome,tried to learn from others ,and nothing. Until saw your video. You explaning exelent!
Thank you so much! Glad to help!
On batery there are two data: voltage and amper/hour.
You talk a lot about voltage, and nothing about amperage.what is amount od amperage that regler send to accu?..thank you for reply.
thank you for the video, very informative.
i have a tomos 150cc nitro and when been fighting it battery drain for a while. So today checked the voltage without a battery installed at the battery leads and its 7-9v when rev'd...i would expect the 14v there. Now once i find the issue stator or regulator, would you know if a stator and regulator would work from a 50cc model? i cannot track down 150cc parts for this.
cheers!
its best to just identify the parts visually and find replacements. chinese scooters often are made with whatever parts are available that day. I've seen 2 of the same year make and model scooters uncrated with different parts. hope that helps. Good luck!
@@Scooter_911 thanks again for the info.
I metered the stator wires while plugged into the wire harness and got 12v and 20v +/- 2 V when reved, then unplugged from the harness it went from 20v to 50v revd. I'm assuming the difference is the system us under load?
I got another regulator from a 50cc (it was the same) and now getting 10-11v rev'd, but still not enough to keep the battery charged.
Would you think swapping the stator from the 50cc would be worth the effort? I don't have a flywheel pully but can borrow hardware store 2-prong pully.
Any other areas of the scooter to consider?
thank you
@@mikec376 you're absolutely right, the readings will definitely vary due to the load of the charging system. Did you check all 3 legs of the stator? Yes if the 50cc stator is identical it's worth a shot. Check out this video I made on replacing stators here th-cam.com/video/pPkbJ0FB3dM/w-d-xo.html
My scooter could not keep up with a radio and running light i installed. So did the ac voltage check and either the yellow or white wire i can't remember which one was charging 30ac volts and up when revved and the other one was way lower I think I teens to 20's. So I have ordered 2 more 8 pole stators like the one in it already. They all check out the same. I could not believe they were all bad. I ordered a 11 pole update stator and it has 3 yellow output wires. Upon checking them 2 of them are putting out 30v and up however the 3rd one is low just like the 8 pole stator. This is driving me crazy. Some people say all the wires should put out at least 40 volts and up when revved. Others have said anything over 12volts is good confused.
So I'm getting spark and fuel I adjusted the valves at 14 on the intake and 15 on the exhaust only thing I don't have is the compression tester and I can't get this moped to start I'm ready to pull my hair out 911.. any encouraging thoughts or direction you could give me would be so freaking thankful I appreciate it and I like your shows keep it up I'm learning things though and I appreciate your time.
Awesome as usual, Garrett!!!!!🎉❤
Hello Sir I got 50cc sym scooter. Last week while driving the scooter sounds different than normal sounds and in few minute the scooter went off and didn't start. Do you think what could have happened.

Good luck friend!
What do you think about the lithium ion battery for a 150cc please give me your take on this.
Honestly there really is no benefit to a lithium battery in a scooter. And they are more finicky to maintain. Its actually not good for them to be charged by the scooter's charging system like a regular battery.
I have a wolf RX-50 that the marker lights don't work but the high beams, turn signals and brake lights work, what could be my problem?
Buddy, I just discovered your videos. You are awesome. The info, super helpful, your sense of humor... on point! Your ending statement "Bucket of bolts and people who work on them are not smarter than you...." GENIUS! and the outtakes to show that effort goes into the videos to get it right. Not to mention "the editing" - The hell behind the scenes that viewers don't see or understand how much time goes into it. If you read this far... Cheers. Just a big high five bro!!!
Ok, I am new to this but your videos are helping me to diagnose our scooter. There is power but it won't turn over. It will run for a day and then stop. Did a valve adjustment and it worked then the next morning it wouldn't start. It just will not turn over the engine. Cleaned the carb and air filter, new spark plug and it originally had a crappy way too high voltage additional light on the front which we removed. We figured it was draining the battery. But, put a brand new battery in this morning and it will crank but not turn over. Any suggestions?
my scooty had broken starter magnet inside didnt turn the rotor properly then stuck at some point , then the relay done some cracking sound and my battery was dieing when tried for too long, i searched for a scooter startor in moto shop but for my surprise was auto stator , find it in new shop , hope it will start when i put the new one , its a Suzuki 150 cc epicuro model
I know this video is old . But i bought a used scooter this past weekend as a proyect scooter for winter.. charging systen is bad voltage jumps non stop . 8 volts to 15 volts . Non stop . . So i ordered new stator and regulator. Still does the same thing. .. maybe is the flywheel ? Magnet ?
Thanks for this vid very informative. I have a Peugeot Looxor 125 and has a problem with charging. Checked voltage giving 14.5v but on lights on 13.5v rev engine. On stator there are 5 pinouts.

Hey Garret ! Thanks for the video ! Good knowledge I just put fresh battery in my scooter its a 1986 Honda elite 150d. As I push the start button the headlight goes out and the turning lights light up more trys tarting clicks some. Although when it does start it dies soon after.
My scooter does the same thing as well
hi garret how do you install a moped alarm i conected.the.battery to it but cant find how to conect the remote start and blinkers
Hello. First thank you for the info in the video. I wanted to ask you a question.
I have a 2007 honda sh150i and when i measure the battery it reads about 12 to max 13 volts when ideling and 15 to 15.3 when turning the throtle near the max. Is that correct in the high rpm or does it have a bad voltage regulator?
Thank you.
Please help!!! I have low voltage at the battery, and it drains it. I measured voltage at the stator, like you did in the middle of the video. When its unplugged voltage is good, about 45v (+/-) but when plugged in, it drops to about 4-5v same at the voltage regulator. I get same voltage at the battery, regardless of engine RPM
Sounds like you have a shorted regulator rectifier my friend!
@@Scooter_911 I have a new rectifier and new stator.. if I unplug rectifier and tone pins, they are all somehow, somewhere connected to ground.. how where could they be connected to ground? Is this even the right way of testing?
My battery keeps showing voltage from 11.5 to 16.8 V when active. The volts change every 30 seconds to anything in that range. Also when fully charged it can still struggle to start but even after a long drive when I stop the engine and start up, it struggles again.
I bought a new rectifier and I am having the same issue. Could an exhausted or defect battery be causing my rectifier to keep sending in fluctuating volts as its trying to keep the battery charged?
Thanks for your reply I appreciate it. Problem here on the West Coast California it’s hard to get parts for kymco -the dealers are all complaining and most are droppin the brand
Thanks for the video! Unplugged the voltage regulator and the ampere dropped! Is replacing the regulator enough to fix the problem?
Yes. Definitely start with replacing the reg/rec and then retest. A shorted stator can cause a lot of issues down stream! Good luck my friend!

So my ground wire from my stator is reading less than like 7 acv while revving the other two seem good is there a way to just fix the ground wire dose it mean it's improperly grounded or something I tried installing two knew stators but the scooter wouldn't start with either of them so I put the old one back on .. mostly just wondering if it's a grounding issue and if so how to fix it if the green is indeed a ground .. or if you know why a knew stator would cause it to not start at all installed same way brand knew same kind of stator ??? Thank you to whoever can answer this knowing what they are talking about ...
If I back probe the stator wires on the regulator should I still have my 20-40 ac voltage?
Hi thk fr the nice video when charging the battery scooter i can drive whole day but leave overnight scooter wont start unless i charging it again the stator is new cdi n ignition coil solenoid r ok does it means that the battery is not good
Great video. I've been lucky enough to visually find drain issues, But loving you refined tactics.
I have a Peugeot Speedfight 4 scooter. When the engine is off, a current of 12 mA is drawn from the battery at regular 2-second intervals. Is this a fault? Could this current be drawn by the immobilizer or ECU system? As a result, the battery becomes unable to start the engine after a week of inactivity.
You are just better than everyone. This is great
I apologize if that's a stupid question but: may the problem be caused by the ECU and not by the stator or rectifier?
Hello, i have a Yamaha aerox 50cc and i get 10volts ac out of the stator wire 1 and 18volts out of the stator wire 2.Normally both wires go to the rectifier.When i give trottle it only get a little bit higher...10volts to 12volts and that 18volts to 19-20volts.
Is this normal ?
Got a yamahaTW200 with such symptom, could you explain how the steps would be modified on a motorcycle? I watched many videos on this issue, really appreciate how orderly you explain things. Thank you!
hi. i change on my 49cc 4T new flywheel, stator, rectifier. obtain 13,3v to 15v but when turn on light voltage drop down even accelerate. please help! thanks
