Okay so i bought a 95 seadoo sp 580 from a friend of mine and he said it would run then blow the fuse on the mpem after a little bit. so i got on here and everyone said the mpem was bad... so i replaced the whole electrical box with a new one, but it was out of a 93 or 94 and it was a little bit different. It had relays on the mpem instead of fuses. but i got it cheap and all of the wires seemed to match up. I went to start it and it tried for a second to run then no spark at all. So i took it to my mechanic he changed a conection it it fired up and ran 4 or 5 times flawlessly and right in front of me. The next day i brought it home and now no spark again??? Called my mechanic back and he said he had no more ideas...So hopefully you guys will!!! Thanks alot
