1995 Sportsman 500, owned since new. Just recently will only start by pull starting, will not start with electric start, turns over great with electric start but no spark. Have changed the battery out, have boosted the battery with a battery charger. Is currently at the Polaris dealer, they have disconnected all the electrical connections from the starter and jumped the starter from an external battery and still no luck. Any ideas?

 

Mine did that,key would not start it but one pull did. I took off the recoil cover and it had dirt moisture in there . Turned out the pulse coil contact face was filthy and it,s flywheel contact point was rusty also, I cleaned up both and its been starting with the key ever since.

I guess because a pull from the pull start makes a faster rotation of the motor it can get a signal between the pulse coil and flywheel even if rusty or dirty,But the electric start turns the motor over two slow to get a big enough charge to get through the dirt and rust. That's my theory anyways.LOL

If the gap betteewn the pulse coil and flywheel may be to wide for the slow turning electric start,but the fast turning pull start can get things going. Clean up the contact faces of the coil and flywheel and close the gap up abit if needed.
