need help no spark!!

yammyman · Mar 4, 2011

hi i got a warrior 350 with no spark. when i first got it it started fine, but over time it got harder and harder to start and the spark was geting irratic weak and inconsistant even though it ran perfect when i managed to get it started, and one day it wouldnt start at all and realized that it had no spark. i changed the ignition coil, cdi and stator and still nothing, i checked the fuses and all the wires and still no spark, i am just so stumped and have no idea where to turn, please help!!!!:argh:

test your stator and coil even though they are new just to make sure you didn't get a bad one here is a manual link specs are in there http://www.yfm350.com/forums/showthread.php?t=20507 if they test good I recheck all the wires completely and clean all the grounds ( i think there is 4)

Especially look over any ground wires.

Ive tested all the parts with my mutimeter and they are fine, they are rmstator haha, but do you know where the grounds are that i should check

i belive there is one on the back side of the motor, like near the rear shock... and the ignition coil should be grounded to the frame where it mounts

I checked the one one the back of the frame and it was shredded so i replaced it but still no spark, any othe wires i should check? also for the ground on the ignition coil should there accually be a ground wire going to it or should it be grounded by being mounted on the frame?
