Does your motorcycle, scooter, or ATV have charging system problems? Maybe your engine has no spark? In this video I will teach you step by step how to test your stator and help you understand how the ignition system works. To understand how a stator works you should also know the functions of the pickup coil, charging coils, and the exciter coil. These all go hand in hand when testing a stator. I will teach you step by step so you have a full understanding of testing and functionality of the stator. specifically found in motorcycles, scooters, and ATV / UTV. In this video we will be using GY6 stators also know as qmj157 or qmi152 engines. 125cc, 150cc, and 170cc stators.

[@arthurtrahan2696]

As a mechanic by trade who has never worked on a scooter or moped, I must say that I found this video very informative. I never knew what a stator did or how it worked. Thank you very much for all the work you are doing to educate those of us that don't have all the knowledge that you do

Just a very old permanent magnet alternator haha. Only its built behind the flywheel.

[@kristinagaddy8504]

What he doesn’t know is the red and black plastic tips come off and he’d have a long prob to use and wouldn’t have to place metal pieces to get connection while testing. 🤣🤣. I’ll be sexist…I’m female and know this & I don’t know a ton about engines but knew this much 😂 Lord. 🤦🏻‍♀️

[@davidpaulsen449]

THANK YOU! I've been rebuilding 70's and 80's bikes for 15 years and someone brought me this GY6 and I've been mind-boggled trying to figure out the no-spark. I've never seen a DC Stator. I've always seen the rotor/stator into the Regulator/Rectifier (and onto the CDI box after '79/'80). All the manuals and test procedures I've found are for testing AC stators and I was starting to think someone hacked into the wiring. Seeing the DC stator on your table and the ground wire and pickup wire with no exciter made me so joyful. I totally get it now. Thanks for making this thorough and thoroughly enjoyable video. Many thanks.

[@M-kill9000]

The gy6 is just a copy of the honda cg125. The rotor/stator and AC/DC cdi-boxes are more or less the same on all the 50cc scooters.

There have been video''s I've tried to follow along or tutorials where the person explains or try to explain what he's doing but I can tell you honestly there has not been one as much your video that I've watched where I can truly learn and remember something and apply it. What a very good instructor you will make or already are. For me a manual takes forever because of my disability to reading and memory loss where as soon as I done reading a sentence I forget what I just read. Bottom line is that you for sharing your talents with mechanical community out here who strive on repairing their own and getting satisfaction when all goes as plan because of unselfish people like you, Thank you

[@bomiller6727]

I have to say i learned a hollere lot from this video. my pops died before he was able to show me how to "really" use a multi meter, so sometimes it feels like iam speaking greek. Then the stators themselves. I didn't know there were a/c and d/c stators. I work on these things quite a bit. So i do understand what you are saying and will be able to apply it to my endeavors. Thank you

[@davidjoaquin141]

Hey Rolling Wrench, Thank you for this informative video. I just changed out the Stator in my Yamaha 2000 VSTAR 1100 motorcycle. Last year my go to bike shop mentioned to me the bike isn't charging properly and its time to replace the stator. So last week I did it, no biggie right but now I know why they want $700 to change it out, its all labor. I haven't started it yet because I'm waiting for the new battery and I haven't put oil in it yet either. So I have the older stator and I was going through the various test that you thoroughly describe, its a 12 volt 3 phase stator. The stator resistance, was 4 ohms, the requirement is .36 to 44 ohms, it appears low and this may contributed to charging issue. But I believe the issue with it is when I tested the pickup coil resistance, it requires 189-231 ohms. There are 2 wires in the pickup a gray and a black, I switched my analog meter to 100k and tested it. Can I assume the gray wire was equivalent to your blue wire and the black is ground? My reading was nothing at all. I assume I'm doing this right, I think the pickup coil is smoked and attributed to the charging issue. Any suggestions or help would be much appreciated.

[@colonialroofingofnorthcaro441]

I just want to say thank you for taking the time to go through some of the minute things which you find in most videos people don't do it's like people think that everybody just automatically knows and I guess from a certain standpoint certain things people should know but when you point out the very small like the dumb stuff which most people would probably consider that's just common knowledge even in those small things when you go around to the big stuff it kind of brings it all together but I just wanted to thank you because for all of us out here that are trying to learn and trying to grow you know in our brains especially when it comes to electrical stuff the very very small stuff and to teach on a video like you're teaching a 5 year old is probably the best way to do it because if a thousand people watch this every one of them for the most part is going to have one little thing even if they knew everything else one thing is going to stand out that oh I didn't know that and I've had several of those just watching this video oh I didn't know that so appreciate you taking the time teach to us like 5 year olds because when it comes to electrical electrical it can be very confusing and the majority of us don't know much about electrical mine a little bit but not the majority and we don't know a lot about electrical it's a very difficult thing especially when it gets into real depth of running 15 different wires and 60 different places and a mile away in one little vehicle it's making it pretty pretty out there God bless

The wire coils on the poles can also short circuit.The copper wire on the coils are coated with a clear insulating coat which thru time breaks down causing a short.You can rewind them using same diameter wire and count the number of rotations.

I’m using a drill since the battery is totally dead. Since my bike has a DC cdi, does the bike need a working battery for it to start?

I just did a 97 arctic cat pantera stator because there was no spark. It only has 3 yellow wires coming from it and thats it. I looked up the specs in a service manual which was .0280 ohms. When I measured it showed me 0.4 ohms. I didn't trust it. Nothing looked to be wrong with the stator. No smell of burn, nothing melted ect. SO I put it back in and figured out my own test. From what I learned it didn't matter any combination of wires. I put a meter across all the wire combinations and cranked the engine. Every combination gave me a voltage of about 9-10 volts. (this is because its not running. Running the voltage will go higher) This is how I knew that the stator was good. Anyway, it ended up being a bad ground to the CDI box. Runs like a champ.

Great explanation. One question: the rectifier on my GY6 engine burn. I replace it with a new one (not original) and the engine fails on middle range rotation. A few minutes later, the rectifier fries again. Now I'm concerned about replacing it again without knowing what is the problem. What and how should I test it?

[@RollingWrench]

Test the stator to see if it’s grounding out

[@Great_XicoZe]

@@RollingWrench No ground escape. 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.

[@atrocitus9804]

Just a heads up, you probably may know this already but on your multimeter the black and red ends come off the probes to allow narrow access. Took me forever to realize mine did this.

[@200xcBruce]

Very well explained. But each stator has same number of charging wires one is all three yellow other is green,wh,yellow. You say the DC has one less since is no exciter coil and is not charging the CDI like on the AC. Care to correct me?

[@brandonmccloskey8710]

So could you use an AC stator with a DC CDI if you only use the pickup wire and omit the power wire that accompanies it and just power the CDI from the battery?

I'm working on a 91 Yamaha WRA 650 can I just unplug the stator and measure voltage coming out of one of the 4 wires that goes to the stator and crank the engine and see if I have voltage coming out of one of those for wires ,when I work on 2 stroke dirt bike I know I should have very little spark coming out of the stator ,so if this engine is cranking I should get some kind of voltage coming out of one of those for wires

What is the difference of a AC stator with a green and 2 yellow wires compared to the green/white/yellow? Will they both work the same?

I have a 80cc Loncin ATV, it has a brand new battery. will not start on it's own, have to jump it but then after running for a couple of minutes it dies, doesnt matter if you're riding it or just idling. Fresh gas, etc. Battery voltage drops to 4vDC when cranking. Thoughts?

thankyou, about to rewind my rmz250 stator, and wasnt sure how to identify it, its 3 poles 1 phase
