i need help
so i was taking out my rats nest today and i pulled my alternator to get to it easier well in the process i arced my alternator on somthing i forgot to unhook my battery. well i blew a fuse(80 amp) its a stereo fuse i have inline with my cable since i have the battery in the back. well i couldnt find any fuses that would fit so i just put a peice of wire in between the 2. so i started it up and it ran fine for about 5 or 10 seconds then died. and now it wont start. my commander doesnt have anything on the screen.i think i fried my power fc but why would it have ran for a bit then fried it? i figure the wire was fine since it would just be like having a solid wire. any ideas?

If for some reason more current was being supplied to the PFC than needed, bypassing the fuse will allow it to fry the PFC.

That said, if the fuse you replaced with a straight bit of wire isn't part of the stock electrical system, I doubt that the shorted fuse is to blame for your problem. Get another fuse (that fits) and try again, I've tried to short fuses before and it doesnt seem to work too well sometimes, bad contacts between the bit of wire and fuse holder etc.
If that doesn't work, then you probably fried something. Just because the car started initially doesn't mean you're safe, the arcing may have partially damaged something. Running the car (ie: supplying 12V to an already damaged electrical component) could have finished it off.
