The ski's a 2007 Yamaha 1100 4stroke. Ran good the other day untill it quit on me. Turned out to be the 30 amp fuse. I replaced it and it seemed to run fine again. Tonight we went to go out on it and the same fuse was blown. We had extras so we went to replace it and as soon as the fuse starts to go into the socket it blows.
I figure its an open ground or a short but i'm wondering if by some chance somebody might have some other ideas because we chased all the wires and connections that we could get to and couldnt find anything suspicious. No broken wires, no small nicks, etc, etc... I'm figuring i'll have to take it to the dealer to have them put their computer on it but thought i'd check here 1st..
Thanks
