I was out riding my 2008 sportsman 300 when i flicked it into AWD (from a stop) and pow! the bike stalled and there was no electrical power at all. had it towed back home and put it back into 2x4 and replaced the fuse. i turned the key on and it started right up, but when i hit the AWD switch it blew the fuse and died again. anyone have that problem? could it be the wiring harness or the coil? I was ridding in some wet terain. any help would be appreciated. thanks
