96 xp 787 won't start won't do anything

I hooked up the battery backwards, It ran fine before I did this now it will do nothing, have i messed up and if I did what did I mess up?

possibly the brain of the machine, but you need to check ALL the fuses, even the one in the ebox, toward back of ski

:agree:

Check the fuses... but the MPEM is probably smoked.

Could be just a fuse. i believe it is a 7.5. i did it once on a 97 gtx. pull all fuses and check those out first

Chances are you fried the diod's in the MPEM. If you replaced the 5 amp fuse with a 10 amp as you stated in your "reported post"...you cooked more then one. Time for a new MPEM.
Also, Reported posts are for reporting a problem in the forum, not a question, already posted in the forum. If you not getting a quick enough response, send one of the moderators a "PM"(private message)
