I'm helping my 72 year old friend/riding buddy with his 08 Sportsman 500. We have full battery voltage at the battery and on the battery cable that connects to the solenoid. If I jump across the 2 posts the engine turns over fine. Also runs fine with the back up recoil. However, it doesn't appear to be getting any voltage to the solenoid from the key switch. Does anybody know of a common failure on these like a fuse or a circuit breaker etc. that supplies power to the solenoid?
