Having charging problems with your motorcycle, ATV, UTV, or snowmobile? Make sure to test your voltage regulator rectifier! Voltage regulators are easy to test and don't even require removing them from your motor. You just need a multimeter and a few minutes.
Follow along with Evan, our Electrical Engineer, as he shows you how to test different types of Powersports stators. - ยานยนต์และพาหนะ
Evan, I have owned quads and bikes for over 30 years and I always just fumbled around with trying to figure out what's wrong with electrical/starting issues. Sometimes I'd get lucky and fix the problem, but usually not. Watching your videos has not only given me the necessary knowledge and thus the confidence to diagnose electrical issues, but it's actually excited me to the point where I want to learn more about these systems. Thank you (and RM Stator) for taking the time to educate people like me...for free!! RM Stator has a life-long customer in me due to both the high quality informational videos as well as the extremely high quality and durable products you produce.
This is the best detailed test and explanation video I've found thus far! Well done!
Glad it was helpful!
4 years later and this is still the most helpful and easy to understand tutorial i have found to test these. Thank you for taking the time to put this together
This was one of the videos I watched to figure out the charging problems on my 2000 Honda VFR Interceptor. Did the other tests and now that I know how a voltage regulator/rectifier really works, I was able to conduct the test and found one leg of the diodes not working correctly. Easy removal, ordered the part, and now we wait...Thank you for the clear, detailed, and concise advice.
I'm not a mechanic by any means and electrical has always caused anxiety, but this video made it much easier and increased my confidence to undertake this.
Thank You!
Excellent. No waffle. No annoying music. Just clear description and facts.
Right on!!!
My 2008 Aprilia rsv has an extra wire on the output side which runs to the ignition switch, is this a separate supply to the switching of the regulator and why is it there ?
Thanks for this post !
I see there were 17 dummies that tried watching this video and didn't like it cause they lacked understanding... Been a while since I've had to work on this stuff, and this video was a GREAT refresher course. Spot on Dude!! Good job! I gave it a Like and saved it to my Favorites! 👍
Great! Glad to hear it helped!
Dude...what a stellar explanation. You cut straight to the chase ...eliminating the weather of the day, your wives menstrual cycle. You dumb it down just-right... Explaining the process well enough that it's understood by an amateur but also providing enough information for the student to ask relevant/educated questions. In all my years of using TH-cam this is the first time I've taken the effort to post a comment. Thank you.
Awesome! Glad you found it so helpful. Appreciate your comment!
The best explanation on the web!!The MOFSET values is what i was looking for!
Thank you for taking the time to make this video. Dirt bike wiring is like a big mystery because it is so simple, but few people have this level of understanding and of those people they do not take the time to explain it.
Excellent video! The clearest and simplest explanation I've seen around. Totally recommended to be watched by anyone wanting to understand how this little critters work
Thanks!
Wiring harness eaten clean through and am having to figure out the whole electrical system and testing all my electrical parts. Evan has the best videos that explains everything in simple terms. Thank you for the videos!
This is Evan, thanks so much! Really happy to hear the videos helped you out!
That was an incredible instructional video. It was clear, concise, and for me made complete sense on knowing how to analyze my charging system.
Hello Evan! I watch a LOT of TH-cam vids. Your video explaining R/R is by far the best educational video I've seen. Very well done. I felt that if I never even heard of a motorcycle I would understand what you were talking about. Looking forward to watching more of your vids! 👍👍👍
Awesome, so glad to hear that. Really happy to have helped you out!
DUDE!! You deserve a prize! Not just for explaining the function of a voltage regulator but for making it fun and easy to understand. Maybe I was just ready for this but you made it easy to understand with this diagram. Now the whole component seems so simple. Now splicing wires to make a change from like the four connecter plug on the smaller 50cc regulator are going to seem so simple. I'm sure I'll goof some stuff up but that will only be because of curiosity in seeing what might work, This was just great!
All I can say is after watching your video I finally get it. Thank you for taking the time to put this video out.
Excellent tutorial! Remembering the drawing in your mind (diodes' direction and battery's plus and minus sides) makes it so easy to understand how to measure between each connector pair and what the results really mean. Regulation was very informative as well. Good job, thank you!
Great! Glad to hear it helped!
best reg/rec testing demo I've seen...thanks for putting this up
No problem!
you really help a lot for us but i wonder why there are still people giving a thumbs down to this video. watching from the philippines.
Glad to help! It's TH-cam, who knows!
Great! Very helpful, very clear demonstration that made me understand clearly how a rectifier works and how to diagnose it as well and the voltage regulator. Thank you very much!
No problem, glad it helped!
Really helped explain what I was actually doing when trying to test my regulator/rectifier. Thank you for the informative video.
No problem, glad to help!
Really great explanation! Working on rewiring a GY6 engine with an 11 pole stator upgrade and have to rewire the bike to accept a 6 pin regulator/rectifier. This is going to help a lot!
Great, glad to help!
Thanks for that guys - away now to test mine. All the best from Glasgow
Best explanation and demo I've ever seen on this subject!! Well done!
Brilliantly explained....one of the best video I have come across for troubleshooting regulator rectifier
AWESOME VIDEO! I'm getting one of these for my generator.
I am impressed with stator set up for checking regul8orz!
The diagrams, explanation and demo were very helpful. Thanks.
Happy to help!
very informative, more than I can comprehend right away. once I think about it for a while it will eventually be understood,
Great, glad to help!
WELL DONE, I loved this, so easy to understand I could do it!
Highly educational video. Even I was able to get it.
I absolutely agree, one of the best explained videos there is on the matter, well done and thanks
Great video on the topic of rectifiers and regulators. Well done..
Should be mandatory viewing for all owning a Ducati :-)
Explained in great detail. Thanks for the video!!!
Glad it was helpful!
Awesome info and explanation....with the setup of machines to stimulate the bike running👌👌👌
Great thanks!
This video is a godsend for troubleshooters with limited knowledge. Bike shops owners hitting the dislike button. Great video!
Omg he speaks english good, he simplifies it and breaks it down. Ugh finally thank God.
Great man, lot of love from South Africa.
You guys are awesome! Thank you!
Thanks for watching!
Thanks brother from Egypt
Very well detailed test. Best I have ever seen.
Thank you!
Great detail instruction
Thanks. This helps a ton! I am working on my 2008 Yamaha F40. The voltage is reading 16.1 volts at running speed. That can't be right.
Perfect explanation! 👍 THNX!
Another great video, Thanks.
Best video I have viewed so far. 🔥❤️
Awesome explanations. very helpful. Thanks
No problem!
Excellent!!! Thanks for sharing this!
Best explanation I have seen, very valuable
Glad it was helpful!
This is beyond excellent. Thank you.
You're very welcome!
Great! Exactly what you need when youre just curious how it works! Thanks
Awesome, no problem!
Awesome video! Thank you.
Excellent video, Evan. This helped me a lot! Thank you! Do you recommend replacing the rectifier/regulator at the same time when you replace a bad stator?
Thanks!! Glad to help. Yes I always recommend replacing them as a pair if possible.
thank you. i actually understood what was going on for a change. cheers. can you demo how to test if its the starter or the solenoid which is failing?
cette vidéo est excellente pour comprendre comment tester un régulateur merci
Thanks!!! very good explanation!
Thanks!
Thanks that was well presented.
Great mini lecture
Thanks!
very good explanation..... Thanks you!!!!
Absolute class video. Thanks, subbed.
Much appreciated!
Explained fantastic awesome video
understood this video very well, thought I diagnosed my bad rectifier well... but my new rectifier tests exactly the same. Haven't installed it yet with hope I can still return it. Thoughts?
Great explanation man! I have a question though. Can I connect my lights(head, tail, turn & dash) directly to the regulator without a battery? Will it damage the regulator/rectifier? I have an old 2 stroke bike that has lights that flicker and wanted to rewire it to DC.
Thanks very informative. Can you post videos on rectifiers, cdi and electrical system of yamaha salient. Its an old model. I kinda like to restore what i have in my garage
Great video,
When I put my black meter lead to batt pos i get 0.5v on 3 phases.
When I put black meter lead to batt neg i get OL for 2 phases but it bells out on the third.
Does this mean the rectifier is broke?
Very well explained.
Great video, will this work the same for a single phase stator set up? (Just less diodes to check).
that a great explanation cheers
Congratulations beautiful video I wanted to ask you a question, we can change the configuration of the stator from triangle to star.I'm waiting for your welcome reply thanks
excellent tutorial
Really good video. A lot of info. Of coarse it doesn't seem to answer my problem though. Lol
I have a skidoo that's popping its main fuse everytime I try and start the machine. I've isolated it down to the stator (ac side) or the regulator (when disconnected the machine starts and runs fine. I've followed your troubleshooting guide and get all good numbers. What's odd is when the regulator is removed from the machine I'm getting continunity between the red wire (battery positive) and the regulator housing. Is that right?
Thank you excellent video.
AWESOME!!!!! Thank you!!!
You're welcome!
Wow, what a video, bravo
Absolutely excellent video!!! Thank you.
The voltage on my KLR650 jumps abruptly between aprox 13.3v to 14.2v at intervals of a few seconds or more. This makes the headlight and dash lights dim and then brighten again at the same intervals. Do you know what might be causing this? The battery is keeping its charge.
I replaced the stock RR with a used unit form ebay with not luck.
No problem, glad it helped! Your issues sounds like a failing voltage regulator. The regulation control circuit is failing, and is firing the shunt switches incorrectly, resulting in large voltage changes. It is also possible you have a stator with an intermittent short to ground. Hope this helps!
NIce video man! Very pedagogic! =)
Thanks!
this is a great video very well expand can help you save money
Nice video!
Good job!
Awesome! Thank you
Excellent video, but I’m still a little confused. I have 23-25 volt ac at idle between the 3 phases from the stator. About 0.2 ohm between the phases with engine off. None of the phases are grounded. So stator should be good I think? I measured the rectifier to be good also. The problem is that the output is only about 2 volt dc. Is the regulator bad?
Great video. I get zero readings when connected to my 3 wire regulator. All I get is the OL on all 4 phases. Ordered a new one so lets see how that one checks out.
Awesome video, very detailed and well explained. I have a question, if you tested the DC output of a rectifier/regulator without a battery connected, would it read the same voltage as the stator? Because there is no reference voltage and the switching would be trying to put out as much power as possible?
Great question. I'd love the answer to that as well.
great vid.thank you sir
No problem, glad you liked it!
very professional and clearly explained. thank you. i have tested 3 reg/rects following the same steps and all 3 passed but when I connect the red wire from the units to the battery's + and the black to the - there is a short (sparks and melting wires). Any ideas why this is so? It's a 97 suzuki savage.
mystery solved. my battery had reversed its polarity. strange but true. the guy I bought it off must have charged it the wrong way or something.
So this is what i need to ask sir, I'm making a wind turbine generator. Can i use motorbike voltage regulator to charge mt 12 volt batt? and will it kick out when my battery is charged?
Awesome! Liked and Subscribed!
Great!
thanks much for this bro👋👋👋
Great videos I understand
Great video. I had a question though. A bit new to this stator rectifier deal. So I got a relocation kit to put my reg/rec in the front of the utv. But having issues with charging now. I'm wonding if the harness has the stator output cables to the reg/rec flip flopped.. say # 1 on stator is connected to #2 or #3 position on the reg/rec connector. This would cause a issue correct? My voltage guage shows 11-11.5 vdc at idle now instead of 12-14 vdc.
When I test the stator it tests good 20vac at idle on all 3 legs, Rev up and all 3 legs jump up 50-70vac. I tested the rec/reg and seems like all 3 legs are reading correctly... .5 at each. But I noticed it's getting quite hot quite quick and low voltage reading at battery and car idles funny.
Thank you in Advance 🤘🏼
Cool tats. Nice job
I own a 2012 husky te 511. so diodes check out, rectifier good. but, the regulator does not climb all the way up to 14.6V . gets to about 13.7 then start coming down. any ideas on what to test next?
thanks! great video
Great video, very informative. But I have one question, I have a 2001 Honda Shadow 750 and the wiring coming from the stator had gotten hot and the connector was in really bad shape. I cut the connector off the old connector and installed a new one. When I found the issue two of the wires were in really bad shape with one of them completely disconnected. I believe I got the wires back in their original positions as it seems to be operating properly but was wondering, does it matter what order/position the (yellow) wires from the stator are in when connecting it to the rectifier/regulator? Can they be in any position? Also, can the system work with one wire disconnected?
Learned alot🎉🎉🎉
Excellent video!
Could you explain why @12:00 MOSFET regulators meter BLACK to Battery + spec will be 0.09-0.11v?
Why are their reading different in this direction?
I really enjoyed the video on testing rectifier/ regulators. I have a UTV that I am constantly having to replace the regulator on. Could you do a video on why regulators may fail and show some trouble shooting steps?
Yes we have some more content planned in the future for details on regulator failures and troubleshooting. Thanks!
gr8 Vid! Thanks! So can a diode go bad by 1 either not conducting at all or 2 both directions.
I'm guessing if 1 diode does not conduct as it should, current capacity of stator would be less.
2 if diode conducts both ways, I guess part of stator could be burned out.
Thanks dude!
Thanks!
Hi Evin, I am working on a jet ski, and have a 5 wire rect/reg (just like yours). So, going by the chart you have made, I only get numbers (all the same ~0.395) in the left bottom quadrant, and nothing on the top right quadrant (other two quadrants are OL). So that means I have three bad diods, but isn't that on the rare side, that all three diods are showing bad showing OL? your advise? thanks.
Very clear thank you
I would also like to see if you can test the regulator with a non running engine, only crank. I have a no spark issue, new cdi but trying to rule out the regulator. Rectifiers work fine.
