After finding no spark on my 2001 Warrior I picked up the manual and went through the checklist. After eliminating everything I check the ohms on the stator. The book says the pickup coil should be between 171-209 ohms. I had 546 ohms. The book says replace the stator. I go to the dealership, he says the numbers are way off, so I buy a stator. I get home with the new stator, measure the resistance, it's the same as the one in the quad. It's an electrical part so you buy it and there's no returning it. I call the dealer he says put it in and you'll have spark, trust me.
I install it and the quad ran for 30 seconds and now I have no spark. I complain to the dealer, he calls Yamaha and Yamaha says the book is wrong. The values should read between 450-560 ohms. I bought a stator only because the numbers in the manual from Yamaha are incorrect. The only thing left that could be bad is the CDI box (black box). I'm hoping someone on this forum has the same quad as me so I can borrow their black box to see if my quad starts. If it does I know for sure it's the black box I need before I spend $270.00 for a new CDI box.
I think Yamaha should take the stator back because it is their manual that is incorrect and their fault I bought a stator that I did not need.
If there is someone in New Jersey that is willing to have me come over and borrow their black box to start my quad please let me know. You have no idea how much I would appreciate it.

 

This may be wrong and doesnt really help you at all man but, When I had problems with my Big Bear The guy at the shop said testing the stator with an ohm meter was a complete waste of time he said that the numbers meant nothing he said the only way to check it was with a peak voltage meter, what ever that it is [img]i/expressions/face-icon-small-confused.gif[/img]

 

If the dealer told you to put it in after you explained your findings, I'd demand that they take it back.
