I just aquired a 1994 SPX that has not been running for a while. I am new to the seadoo scene. The 5 amp fuse on the electronic module when I install the battery. I looked for a short but found nothing. The motor cranks fine with the plugs out but with the plugs in it cranks VERRRRRY slow if at all as if the timing is off. I disconnected every connector and found that the 5 amp fuse will only blow when I connect the ground from the CDI that goes in the main electrical box. With this I believe that the CDI unit has a short causing the fuse problem as well as the timing issue. Can I get some ideas from anyone that has seen this before. Thanks
