So I'm not a mechanic by trade but i deffenetly can work on my own stuff but I have a 2010 grizzly 660 special edition that when I would ride it , it would drain the battery to where all electrics would quite working but I could still pull start it and drive it and if I charged the battery it would run perfect for about a hour and then do the same thing again all the wires look good so I'm thinking it might be the stator which I've been trying to figure out more about the stator cus I've read that it is in the motor and u have to take the motor in half pretty much I'm hoping it is much easier tho any information would be helpful

Welcome to GC from Maine! There is a ton of info on this forum about stators. Do a search and you will find it. Some of the other members will know how to put a link you can follow to the info. Good luck!

I agree with mainehunter, former Yamaha techs like our user dezz would be a great person to ask about this. He has helped me a lot!

Test for voltage on the battery terminals with the engine, above idle rpm. Your looking for 14 volts.
If your getting 14 volts or so, then have your battery load tested. It might be bad.

If not getting 14 volts, first test the resistance of the stator wires. I can't remember the numbers you should see for resistance.

Go to tradebit.com and download a factory service manual. All information you are looking for is it in. Changing a stator is not hard, but you first need to make sure it's the problem using a multimeter. If it tests ok, then the voltage regulator could be the bad part. Unfortunately, there is no testing this. You must replace it to test it.

Again, download a factory service manual. It's less than $20, but invaluable in information.
