![HOW TO TEST A STATOR / WHAT IS A STATOR [step by step] GY6](/img/n.gif)
I get at least a comment a month from viewers saying the finish voltage is still too low at 13.3-13.4 volts at 5000rpm. The battery in this bike is lithium-ion and you will see just before I start the bike for the final test it is giving 13.2V open circuit. This is the highest voltage this battery will take or give is 13.5 max (2.25V X 6 Cells). Your own end voltage may vary at 5000RPM due to your battery's state of charge. Also, lead acid batteries will absorb and float charge at higher voltages than lithium-ion ones do. The Honda Factory Manual states the voltage at 5000RPM with headlight on should be between 13.2V and 15.4V This range is necessary for the difference in the battery's state of charge during the test. If your battery is newer and fully charged before you start the test your voltage reading WILL BE LOWER than 14 volts. This is because the battery does not need the stator current at that time. A discharged battery will take higher voltage and this is what your regulator rectifier is doing, measuring the batteries voltage to determine how much current it needs to send to the battery. If your voltage is above 15V for more than a few seconds, your battery or voltage regulator are faulty. Some have commented, referencing the Haynes or Clymer manuals stating there should be 14V or 15V. My advice would be to download the Honda factory manual and sell those others on ebay. If you are confused about voltage and current, look for my comment on "ohms law" below or google it. Voltage only goes up if the state of charge in the battery is low. Enjoy!
I’m a Honda CBF 1000 owner since 10 years now. Stator problems on this bike is a serious disease !
My last repair was with an Electrosport stator as in the video. It shows same low values (between 13.2 and 13.6) . The original Honda OEM shows 14.2V at idle.
I contacted Electrosport and they confirmed that their stator produces less power at low rpm to prevent stator from overheating.
This can be a huge problem when stuck in the traffic as when the fan kicks in the voltage drops under 12V and the head lights starts blinking.
It does the same with both lead acid and lithium battery.
@@ziedlazghab8014 Thanks for the feedback!
Hay Rod, A dab of sealant over the loom rubber bung is also a good idea as well a dab on the crankcase joins ... As long as you see over 12V DC at the battery with bike running/lights on main beam, there's no cause for concern, Voltage output from any stator is all about the amount of winding per each phase on the stator, obviously Honda over did the wind, hence OEM units kick out too many electrons that the loom, R&R has to bleed of as heat, best mod along with a new stator is to install a Mosfet R&R, Yamaha fit a quality unit as OEM & plenty around on eBay as used units, also bin the stator loom connector & solder each phase & heatshrink over the joints .... Lithium Battery isn't a good mod on old bikes, system can't ever fully charge a lithium, so you'll never see a fully charged Battery, also you'll need a Lithium spec R&R & a lithium spec charger.
Hi mate greetings from GB, thanks for this posting this information.
I'm contemplating buying an Electrosport stator for my Aprilia RSV but keep finding very negative reports regarding longevity.
I hope your replacement is still good, but if not how long did you get from it ?
I didn't realise this whole stator failure thing is so wide spread, I'm beginning to consider rewinding myself...
Best regards Mitch.
Hi just replaced my stator great video .couldn’t have done it without your video.thanks
Thanks for the feedback & the view! Hope you check out the rest of the channel!
Watching this two tutorials about checking battery, coil... I've learn everything what was wring with my motorcycle and you was right. Thank you from the bottom of my heart!!!
Great to hear this worked out for you!
This is the second of your productions I’ve seen. The level of detail and technical accuracy you provide are absolutely professional quality. Add to that, the tips to help the mechanic achieve a best quality repair and to avoid frustration and wasted time- pro level instruction. Providing a ‘heads up’ to expect the magnets’ resistance to removal of the stator cover will likely help a novice, avoid the confusion of wondering if this is normal.
Much respect for your work as a technical educator 😎♠️🎩
Thank you for the complimentary comments & views! Please check out the channel page for the latest videos👍🏍
This video helps, thanks for being in the back pocket
Awesome feel free to share it with your friends! Check out the channel for more...
Great video sir.. a lot of info gained from your video.. Thank you very mush Sir.
Excellent tutorial. Just bought a 5th gen with 18k miles, 1 owner. Looking into replacing the regulator/rectifier. Sub'd. Thank you.
Thanks for Commenting, Ride Safe!
Grandioso !!!!! Muchas Gracias
Excellent. Thank you!
Thanks 👍
SUPER helpful video, thanks!!
You are welcome! I hope you will check out the rest of the channel as there are a lot more videos on different subjects...
@@RodRidesWrenches Indeed I am! Was watching the video about testing the battery/stator/regulator so I can do that today. Again, thank you!
Another brilliant video mate thank you!!
Thanks Again!
That's a good video that. One of the best I've seen. Gave me more confidence to do it, rather than just relying on the old Haunes manual
Thanks for Liking be sure to check out the other motorcycle maintenance vids on the channel!
Great video !!!
Very clear and precise Information.
Gracias amigo !!
De nada! Check out the rest of the channel for more instruction on a wide variety of motorcycle maintenance! 👍🏍
Awesome video! I'm about to do this job for the first time and you've helped from start to finish!
Do you have a linkf or the new stator that you used?
I bought this one off Ebay because none of the shops I typically use, fortnine or bike bandit had one available, The seller is still selling them. www.ebay.com/itm/324058928953
I have recently bought a number of parts from Fowlers out of the UK and found their customer service and stock level to be leaps & bounds beyond anything I've found in North America.
Good video on testing and replacing. Was this the original stator you replaced? Approximately how long is their average life span? Rectifier?
Excellent videos. Thank you. I have an older 1991 Ducati 907ie and only have two wire coming from the stator and to the R/R. You mentioned a little about a two wire system. Would the test to check to the lack of grounding for the stator be the same as a 3 wire?
Hello UNPOCO MAS, yes the method would be the same. You can also use the method in this updated video that also explains the two wire vs three wire stator. th-cam.com/video/KpmvUvpRCEM/w-d-xo.html
According to Haynes book, regulated voltage output have to be 14.0 to 14.8V at 5000 rpm.
Not according to Honda! Standard Voltage is13V-13.2V Headlight on @ 5000RPM Otherwise Voltage should not exceed 15.5V DC. The Battery used is a Lithium which also may impact the multimeter readings since it is fully charged when before starting the bike & testing in the video Lithium Ion batteries have low internal resistance. If your battery requires more than 14V then it is not fully charged or has lost some capacity and or has increased resistance. State of Charge of the battery plays a roll in the output of the regulator. A weak battery will draw more current from the regulator & stator, to raise current the regulator can adjust voltage. The relationship between voltage, current, and resistance is described by Ohm's law. This equation, i = v/r, tells us that the current, i, flowing through a circuit is directly proportional to the voltage, v, and inversely proportional to the resistance, r. In other words, if we increase the voltage, then the current will increase. If we increase the resistance, then the current will decrease.
Thank you so much for the video. What síntomes Will show on the bienvenido, if you ú have bad stator? Thank you
Sobre on the bike
Your bike will shut off at the worst possible time and not start... Seriously check your battery voltage at 5000RPM with headlight highbeam on! Should be between 13.2 and 15 Volts. Thanks for Liking & Subscribing!
Hello there, thanks for the video! The link you have provided for the stator points to bikersrun website, I wanted to know if you've dealt with them in the past? And what's the quality of the parts? Thanks again 😊!
I recommend them 100%. Quality is comparable to any aftermarket product. It's not OEM quality but it's less than half the OEM price! IMO well worth it since I've found exactly the same stator and gaskets for twice the price on other websites. Biker's Run has really great service & pricing but expect a few weeks of shipping from order to delivery since the parts come from the factory direct to you.
@@RodRidesWrenches thanks a lot for the quick reply, I really appreciate the feedback, I'll go ahead and order from them!
Do you have to drain the oil before removing the engine case? Thanks
I don't because I want to make sure any debris from the gasket comes out on the oil change if it works its way down. So I top up the oil after repair, test run then change oil. Good Luck!
But is there going to be a lots of oil coming out?
@@Motogreets not this spot
i'm sure this has been asked, but how many miles did this go before it failed? there's really no other way of finding out this before it happens? (other than seeing it on a voltmeter)? i have a 5th gen, so far so good...at 30k, i've replaced the battery and i see its charging over 14 volts (but you have to rev the motor up to 2,000 rpm to see the charging capability as its at idle its just over 13 volts
They are all over the place but most fail before 50,000KM. Thanks for the feedback, liking & subscribing!
if you test the stator via multitesteter in continuity...what value did you get to tell it's faulty or or not?
If there is any continuity, there is a fault. There should be no connection between the stator leads and ground. If there is the insulating poles have broken down. See if this explains better. th-cam.com/video/KpmvUvpRCEM/w-d-xo.html
Kia Ora, is it an OEM Stator? and where did you buy it?

Is using a torque wrench for this absolutely necessary?
Short answer YES! Break a few bolts off, the torque wrench will pay for itself 100X over. I always use them after learning the hard way...
Hi, can I ask you? In around 13 minute in video you are applying some kind of oil or vaseline. You called it RTV. Can I ask what rtv is? Thanks a lot
Room Temperature Vulcanizing Silicone, this is a common gasket sealing material found in all auto applications and is available at any automotive store.
@@RodRidesWrenches thanks a lot.
Statör zayıf bu voltajlar çok düşük 14.1-14.5 volt optimum
