No power, full battery, no blown fuses.

Hello all,

I was going to change the start stop button on my 2004 seadoo gtx super charged. I tried to remove the dess post and heard a small click by the fuse panel. I stopped and trying to start the ski and found I had no power at all. No beeps, no instruments, nothing. I am lost on what to do next. I made sure the battery was charged and tried different keys. I am thinking it’s the dess post but don’t want to throw parts at it and hope. Thanks in advance for any help.

Hey Jeff, I had a similar problem. Try this. First, verify your battery is serviceable. Next, put your lanyard on the D.E.S.S. post and wiggle the forward AMP electrical connector on the MPEM. Let us know if the ski comes back to life.

Omg thank you that worked. Anything to keep this from happening again?

No. Here's the bad news. That connector is pulling away from the motherboard inside the MPEM, and you are going to need to replace the MPEM. I replaced my MPEM (search your MPEM part number on Ebay), and my ski is working great again.

Thanks so much for the help. I will look for one to replace it.

Yes I was fighting this problem for many months. First I changed the starter solenoid, but that didn't fix the problem. I'd ride around and all of the sudden the ski would die, no gauges, no power, no nothing. I'd pull the seat off and wiggle the wire harnesses on the MPEM and the ski would come back to life. When I looked closely, I noticed the connector on the MPEM was moving. I've been GTG every since I replaced the MPEM.
