Sooooo had the ski out yesterday off Cape Henlopen and aired the thing out real good for a couple hours and came down hard a few times. All of a sudden the ski got real sputtery for 10 seconds and then just quit. no beeps from the key. dead. got in on the beach finally, battery strap hooks broke. battery was flopping around in there for god knows how long. positive cable was loose. tightened that. still nothing. pulled the fuse block and the MPEM fuse was blown. Tried a spare. blown. doesn't blow till i put the key in. tried unplugging VTS cause i heard that can short stuff but that aint it. any suggestions to narrow this down? i'm hoping its not a fried computer....thanks
