I have a Wave Runner that was running fine and then would no longer start. Dead as a door nail, no clicks or anything. Battery is new this season and meter shows good voltage. There is no voltage at all at the main fuse. What is between the battery and the fuse and how do I get to it? It look it may be in the black box that the fuse holder it in, but I tried to loosen the 2 bolts in the batter box that looked like they were holding that black box but they were very tight and didn't want to force them. Am I on the right track? Any help would be much appreciated!
