Please Help Diagnose **video**

2003 Seadoo GTX SC. There is something wrong near the wires in the video. When I move them around, I can hear the sound of, what appears to be, an electrical connection being made and lost. There is also a faint hissing sound you can hear when the power is on.

This error is causing the key to go on/off, as well as the whole dash. It will also kill the motor if running. Any ideas what this could be? I don't know what all the parts here are called. Maybe it's the "brown thing"? lol.

Any help is appreciated. Thanks.

ETA: Both fuses at the end of the wires are good.

That brown thing is your starter relay. That sound is the starter relay being bridged inside and trying to engage starter and turn engine over. ( same sound as when you press the red start button to start engine on handlebars)

Unplug that little 2 wire connector on the starter relay. It has a yellow wire and a black wire. Then do your wire wiggle test again. Does it still make the same noise??

Ok, I unplugged it an no change. Same sounds, same behavior. My wires going into the connection were purple and purple/yellow.

Those are the two main 30 amp fuses. One goes to the rectifier and the other goes to the MPEM. The fuses may be good but you have a bad connection in that area. Sometimes wires corrode at the terminal crimp or from the inside out so it will take close inspection. Probably the main wire that goes to the MPEM as a bad connection there describes your issues.

Probably not your solenoid as a bad connection there won't kill the machine while running but a bad connection at the main fuse will.

I was afraid it may be a bad/corroded wire. Ugh. What is the fix for that? Locate/cut/patch?

Interesting, I would unplug 1 fuse at a time and replace until noise stops and/or unplug a main connector in that area.

Something is going open and close circuit during your wire wiggle test.

The noises you hear are normal at initial power on. It is just cycling power on with a bad connection.

Not a bid deal to fix, find it and repair the connection. Usually will be at the ends at the terminals. May even be at the MPEM connection.

I think I really only see the one big red wire that goes from the top connection at the 30amp fuse down to the MPEM. I guess I will cut off the shrink wrap and loom and look at it.

Before you cut into anything, you can isolate where the bad connection is by holding the wire still and bending/twisting the terminal end to get it to cycle. I've seen quite a few bad connections right at the fuse blade, wiggle twist the blade. Even seen fuses that looked and tested good but had an intermittent break in them. I'd look in that area first.

Good idea. Thanks.

I noticed one of the fuse clips/prongs that holds the fuse in was a tad loose, bent it back into place with a nail. Cut the heat shrink off of the wires and looked around, but didn't find anything. Moved the wires around a little and repositioned them.

Now--I can't replicate the problem. Seems to be working. I don't think it would have been the fuse issue, since I messed with the fuse connection quite a bit earlier, but I guess it could have been.

I'll try again later and see if it cuts out, but tried several times to make it fail and it didn't.

ETA: I also pulled the rubber plugs out of the bases of the fuse connections. Everything looked good in there too.
