I'm having a problem with my Seadoo, no beeps, nothing when pressing s/s button, no gauge (but may be broken). I found what I believe to be a ground wire loose but don't know where it goes and the manual only shows the battery ground. All fuses are good, battery is fully charged but nothing, replaced the starter and the solenoid. Please help. Im a noob but used to race a dirt bike and had to maintain it. Im just not sure how to check the MPEM and other electronics. Thanks for the help!! Would sure love to get this running before it gets cold!!
