okay, i have this 99 warrior in my shop and i just figured id let you guys know whats going on with it. It wasnt getting any spark at all so i ran through the usual checklist and went from the plug all the way to the cdi. It all checked out good. Then i remembered a quad i had fixed in the past (arctic cat), and thought id try unplugging the voltage regulator. and Biggity Bam now its got the prettiest blue spark youve ever seen. It even stretches out over a half inch gap. So then i tested the voltage regulator/rectifier and sure enough its bad. Just figured id let some of you guys know about this little check to maybe save some headache. Later

 

i have the same problem with my warrior. just put a new coil in it after my old one burnt up and came to find out that now i have no spark. i have checked the continuity of the orange wire from -

 

the coil to the cdi just to make sure there were no broken wires and all tested good, so thats where im at, now whats the voltage reg? and what do i unhook? please help me....

 

okay so i got an update on this warrior and it is fixed and gone. It turns out that the red wire coming from the stator where it plugged into the cdi was rubbing the frame and grounding the exciter coil out making it fire inconsistantly. so i wrapped the wiring real good and put plastic shielding around it with even more wrap and then replaced the voltage regulator because it wasnt charging correctly and its good to go.

 

i hate finnicky machines.diagnosing one now. will try the regulator trick. thanks. btw the regulator sits next to the cdi at the back on later models, otherwise it is the electrical component with cooling fins.

 

yep thats it

 

im in sum desperate need of a lil help.i have a 04 yamaha warrior 350 its been bored over 1mm,its not getting a spark,i had spark but didint have gas rebuilt the carb and now have no spark.i had the stator off today it looked alittle worn,the coil looks fine,ive checked the whole wiring harness no slpits or splices at all.any and halp help is greatly appreciated.

 

i took the regulator off and turned it over but it still has no spark.any help

 

i have a yamaha warrior 350 bored 50 over and it had spark and it would lose it and about 5 minutes later i would see if it had spark again and it did and then it lost spark and it had no more spark after that but i dont now if it is the stator or not because with out the battery when you pull start it the lightes would come on so i dont now.so please if you could give me some advice?

 

sounds like a loose connection. check your wires and connectors.
