I have a 1996 Seadoo Xp 787 and I had the battery out of it for the winter to keep on trickle charge. I had started the ski about amonth ago and everything worked fine.
Today was a nice day and i was considering maybe taking it out so I put the battery fully charged back in. Well it was hard to see down in there and the battery i have has such small + or - signs makeing a stupid mistake i wasnt paying much attention to where the terminals were being plugged in , I herd some clicking sounds but assumed that was normal during initial contact of battery terminals, so i connected the battery cables up and put the key in no beeps or anything. I got my head in there and Realized the cables were connected backwards. So i hurried and unconnected and connected the right way Red-Positive, Black-Neg. and put the key in no beeps or lights/cranking Dead as a door nail, so i searched the forums on pwc today and others and some folks said the 5 Amp fuse could be blown on the MPEM. Took the lid off and sure enough the one Five amp fuse on the Mpem was blown, and the other 15amp on the mpem was good SO i replaced the Fifve amp with a new one and still no beeping or cranking?? Now im stumped is the MPEM Fried. Put a Volt meter on fuses and they were getting juice so it couldn't be the other 15 amp fuse in the black box near the battery no wires or anything anywhere look smoked??
