Does the mpem have the 15 amp fuse connected to it?

This is what it would look like. You can see the two fuses on it

My ski only has the 15 amp fuse on it. I did leave it at a shop to get repaired. But, they didn't do anything and I didn't want it to just sit there so I took it out. I didn't notice the mpem wad missing.

Before i tried to work on those electronics i'd ask myself why it's so dirty inside... I just opened mine from the 95 xp and it was like the day it went together... could eat off the inside. It's supposed to be water tight so if it's wet inside (I think i see rust on one pick on the Ignition coil) there could be other parts that are suspect. I know that some are supposed to be water tight was well, but moisture and electronics don't mix, and so we like to put them on the water in a hull that frequently has water in it of course.
Anyways, I will send you the wiring diagram pdf... sorry i missed the missing MPEM... didn't look at the first few pics. Only the one last few trying to focus on wiring. Didn't see the forest through the trees.....
Here is the full description, updated and (i hope) corrected.

So it looks from the diagram that the Solenoid lug that has all the black wires is just a common ground. It's not even part of the Starter solenoid in so far as it doesn't connect to it internally other than via the ground though the MPEM.
So to address all the black wires on the starter solenoid, there are 5 black wires that go to the lug on the Starter Solenoid (VTS Module/Ignition Coil/Starter Solenoid/Rectifier and the ground from the start/stop button), and one black wire that comes out of the stater solenoid and goes to the MPEM.
For the Starter Solenoid: The two heavy red wires go to the starter and the battery. The Black, Yellow&Red, and one light red wire go to the MPEM. The other light red wire goes through the VTS module which is mounted on the cover of the e-box and has a 15 amp fuse in it.
For the rectifier... It has a black that goes to ground(on that lug that is part of the starter solenoid) and then a Yellow and Yellow&Black that goes to the harness that goes to the engine. It also has a red wire that goes to the MPEM.
For the ignition coil....It has a black that goes to ground(on that lug that is part of the starter solenoid) and then a Black&Red wire that comes from the MPEM and splits to the Ignition Coil and then to the same wire harness that the Rectifier's Yellow and Yellow&Black go to. The final black wire from that harness goes to ground(on that lug that is part of the starter solenoid) The two heavy black wires are the spark plug wires.
For the VTS Module: The purple wire comes from the MPEM and splits twice on the e-box cover side (and once before it gets here into Purple&Tan), with one going to the VTS Module, one going to the gauge cluster(via Harness) and the other going to the up/down button (via Harness). The Green&Orange and Blue&Orange wires from the VTS Module go back to the VTS Motor. The Green&White and Blue&White wires go to the Up/Down switch in the same harness as the one purple.
The other MPEM wires:
Tan comes out and splits to Tan and Tan&Black. Tan goes to motor/thermo sensor switch. Tan&Black goes to Buzzer.
Purple&Tan split off the purple wire and goes to the buzzer.
White&Gray comes out and ends?
Red&Purple comes out and ends?
Yellow&Red (2) (i) goes to start/stop switch
---------------->(ii) goes to starter Solenoid
Black (3) ----->(i) comes from the Safety switch
---------------->(ii) Comes from ignition coil
---------------->(iii) comes from the Starter Solenoid
Black&Yellow goes to the safety switch
Red (2) ------->(i) one comes from the starter solenoid
---------------->(ii) One comes from the Rectifier
