Greetings everyone! I hope you are all able to get out and hit the water lately, we have had nothing but rain and cold in the mitten and had my first day out on the water (or at least the launch) on Saturday.
So to start off the model I have is a 1996 Seadoo XP with the 787
My usual process for going to the lake is to do a pre check and fire the ski up before I even leave my driveway. I usually run it for about 5-10 seconds max, to make sure it will at least start. I did that and made my way to the lake. Got to the launch topped off my oil backed into the water and weent to fire up the ski. It turned over, fired and ran for a split second then died. I tried to fire it up again but it did not crank after pushing the start button. I did not hear the solenoid click either. I pulled out of the launch and went home
I did a little bit of diagnostics at home and have an idea of what I think is wrong but i want to see some opinions before i drop the money on this.
Checked battery voltage - 12.4v
Checked Fuses - All OK
Checked wiring making sure no connections were unhooked - All OK
Jumped starter solenoid with a screwdriver - starter cranked engine

Jumped starter with screwdriver and it cranked the engine, starter is good.
So i looked into the wiring from the white electrical box in the front. I checked the solenoid to see if the yellow/black wire had close to battery voltage, it had 0 volts. Traced the wire back to the electrical box checking ohms from the white connector on top of the black ignition box in the back of the ski to the connector just before the white electrical box in the front I had like .4 ohms.
Went back into the white electrical box and ohm checked the yellow/red wire that goes to the starter solenoid (i think) and checked ohms along the way, all were around .4, until i got to the fuse in the electrical box (mine had a 7.5 amp in it for some odd reason, but i think it takes a 5) and there was no continuity between the fuse holder and the wiring to the starter. Fuse looked ok....
So without having a diagram (im having a difficult time finding one thats for the correct model i have) and doing just basic checked it seems as if im having an issue with my MPEM...
Does anyone think this diagnostic sounds correct? The electrical system in this seems pretty confusing to me. Is there something im missing?
Also does anyone know where i can get good diagrams for the electrical system on this ski?
