Working on a 1998 Polaris Magnum 425 4x4. I not getting any spark at the spark plug. I have replaced the main coil the spark plug wire is on, the pulse coil on the magneto, and the cdi. Still no spark. Any ideas. I also found the ground strap that tied the motor to the frame was broke. fixed that and still nothing. The book I have that covers a lot of atvs says there may be a breaker or a fuse but I cannot find one. Only other idea I had was if the stator was bad, unless it all just needs cleaned up real good. I dont know.

Did you replace the pulse coil meaning new ?
Yes. Even after I replaced I realized it probably was not bad because it metered the same resistance as the old one.
Where did you buy the old one from rick stator or rm stator
The old one was on the motor when I got it. I bought it offline. I was looking at the wrong spec when I thought it was bad.
Is there a way to test the stator?
Yes but the firing comes from the pic-up coil. How many and waht color of wires are on the stator not the pulse coil.
I am not sure about the number of wires or colors I am not looking atn the atv right now.
Does this ATV have a pull start ?
It does have the option to pull start yes but it has electric start as well.
Can u meter the wires coming from the pulse coil as it is turning to determine what is wrong? I am also wondering about the spacing of the pulse coil?
u still there
I have to get back to work. U can email me and I will get it at XXXXX@XXXXXX.XXX.
Will it fire using the pull start , ground the plug to the cylinder and watch for spark.
