Ok I will cry to whoever listens and possibly helps.
I have a 425 Magnum 4x4 I believe about a 94 or so, possibly older, I have found that all the 425 engines are the same, I let a friend hunt with it and he complained of it would not start peridocally, when I got it back it would not start at all!
It cranks, will not spark!
I replaced the spark plug, CDI, Coil, and tested according to a ohm guide on bickbuckatvs.com (also where I bought the CDI and coil) and all checks out ok. I unpluged the black kill wire still no fire.
Currently I am removeing the flywheel to inspect the staitor and check for debris.
Any ideas on what may be wrong?
HELP!
Thanks Tons

does it have a pulse trigger coil? what tells the cdi to fire? that may be your problem.

There is a "trigger" mounted on the stator plate that sits next to the flywheel. It triggers the spark as the flywheel turns.
Many times on these older machines the little bolt holding the pull start spool on will come off and it will get tangled up between the flywheel and the "trigger".
This bends the trigger away from the flywheel and you either loose spark completly or it sparks only sometimes.
This is always the first thing to check on a 425 when you loose spark.
And to whom it may consern the low coolant sensor has NOTHING to do with loosing spark.

If this bolt was not your problem remove it and put some loctite on it anyway while you have the cover off. It can still cause problems later if you don't loctite it NOW.

Don't let the hp numbers fool you. Its all in how you get it to the ground. Clutching clutching clutching!

Another thing to check would be the ETC it could be stuck or shorted out.

From to whom it may concern, this comes from personal experience, not a guess. The 425 would crank and not run, refilled the coolant and not a problem since. Coincidence I don't think so.Originally posted by: cornbread2

There is NOTHING on a Polaris 425 that shuts off the spark if the coolant gets low. You can completly drain the coolant and they will still run.

The 425 had a sensor in the rad. that works the fan and a sensor on the engine that works the "hot" light.
They have no effect on the spark.
