88 pickup 22re.I screwed up .I was helping friend put in new alternator and did not disconnect negative battery cable.When i went to disconnect wire that is nutted on to alt. I got a firework show.Checked fuses in engine bay and 80 amp fuse looked blown.I tried to pull out ended up breaking thing to pieces.It does not appear to have 2 male posts coming out of fuse box like other fuses.Whats the deal and how do I fix.:whoops:
