Does it look so bad that it couldn’t be fixed, if your not going to try the diode fix I would like to give it a try, I would pay the shipping and give you whatever is fair.100% a MPEM failure. after replacing the fuse it ran for a bit on the trailer and the MPEM released smoke magical smoke. Strange the fuse didn't blow while on the trailer just fried the MPEM. But I figure it was already on it's way out.
Other than that, the GTX was running great and the GTS was a champ and towed it back in. Maybe I can swap it out and get it out one more time before the weather turns.
I've rebuilt GM gauge clusters before. Never anything that melted like this.Does it look so bad that it couldn’t be fixed, if your not going to try the diode fix I would like to give it a try, I would pay the shipping and give you whatever is fair.
My volts were pretty low while it was running.You had between 12.34 and 12.6 volts while running, that’s very low. I have no idea barely at all about all the electronics but when searching “blowing 5 amp fuse” I did see a number of posts where the rectifier and the stator where suspected. Those volts are to low while running, I would wait until Someone who really knows what they are taking about replies before you put that MPEM from your other machine in, in case the issue damages it as well.
You could be right, just wanted to give you a heads up in case it was something that could damage another MPEM. I bought a few non running skis to work on, just to learn for a hobby and almost all of them ended up being fuel issues so I know next to nothing about the electronics. I guess that’s a good thing, lol. Anyways, hopefully someone else chimes in here, it’s a slow time on the forum this time of year so not as many replies as in the spring and summer months.My volts were pretty low while it was running.
I know the mpem failed but something could have caused it like the rectifier or stator.
From the reading I've done seems when the 15amp fuse blows that is a more common stator and or rectifier issue
I just need to get it running long enough to winterize it with antifreeze. I store these in a shed and it gets very cold here in MIYou could be right, just wanted to give you a heads up in case it was something that could damage another MPEM.

It used to get cold here in eastern Ontario but anymore we are lucky to even have any frost in the ground, I’m always praying for cold and snow for snowmobiling. If you look in the manual available for free at seadoomanual.net it will show you how to winterized the machine without starting it. If it comes down to that and you don’t get it going before the cold weather, you can still winterized it. I do the same as you usually, just start it up, and put biodegradable antifreeze in the water supply to engine.I just need to get it running long enough to winterize it with antifreeze.

Thats how these have been done for nearly 30 years now. These sat for a while and my dad bought a new gti. So he wanted to sell these.

It’s really to bad, you did everything right. Just bad luck but hopefully it gets figured out and isn’t to costly. Those machines still look greatThats how these have been done for nearly 30 years now. These sat for a while and my dad bought a new gti. So he wanted to sell these. I decided to get them.
I went through the carbs and fuel likes this year and new wear rings and jet fluid changes. Everything was running great until this gtx decided to give me issues. These were mostly run on a really small lake up north.
Thanks my dad took good care of them. It's not too big of a deal. They are older amd stuff breaksIt’s really to bad, you did everything right. Just bad luck but hopefully it gets figured out and isn’t to costly. Those machines still look great
Thats what I was thinking. At idle it was bouncing from 12.5x to 12.7x consistently. Never got over 15v which the manual states is badRight on, volts seem ok
