Had the relay problem happen to me last year, 20 dollar fix and all was good.

Now this past weekend after a short trail ride and then bathroom break, i went to start her up again and had nothing. I found that i blew a (10) fuse in what is was called the start assist spot (not electric start). After putting a new fuse in i noticed my headlights would go right away but my sled would start just fine on second pull. However, when i shut my sled off the headlights would stay on(not good). I took the fuse out after each ride and unfortunately took it into dealer cause i had no idea what problem was.

Dealer advised that underneath my fuse box the wires, which he said are positive, were rubbing up againt the metal frame, the negative. After some time the wires rubbed enough to cause a short, which blew the fuse. It will continue to blow fuses or keep a charge, and drain battery, until you either replace the harness (expensive) underneath the fuse box, or tape up the wires for the quick fix to ride..

Hope this helps--
