1996 seadoo xp no spark no gauges

[Logan.mchose]

I rebuild an xp, whole engine, most components. Lost the OEM MPEM in the mail so I got an aftermarket one. Seems to work, it beeps twice when key is on and will turn over fine. I have no spark or gauges though. Replaced coil, starter solenoid, stator, and flywheel, I have no idea. Maybe the rectifier? Holder relay? CDI? I might clean all the grounds, I did them in the engine bay but not the MPEM.

Also I did have a random grey wire in the new MPEM but the only grey/white wire go to DESS so I plugged it in.. even tho it says “tachometer” on the aftermarket wiring diagram.

With an aftermarket MPEM I don't know if we will be much help. Those things are known to be questionable.

Gotcha, I also bought another OEM one but when I put the key on with that it just keeps beeping.. I think bc the key isn’t paired to it. I might try the OEM one again not sure what to do.

Yes, you have to pair the lanyard to the MPEM, that is what the single beep is telling you.

Yeah that’s what I thought. I wish I could do it myself I’d be golden!

Did you clean the grounds at the mpem?
