No Dashboard Lights, No A/C, No Radio and Won't Start

It's likely that you blew the mega-fuse, it's the big one in the distribution box under the hood. It's bolted in.

There are probably mega fuses under the hood , A multi tester is useful for electrical problems

After much reading and looking at videos yesterday, I finally found a video that described exactly what I did by dropping the alternator wire onto the metal covering my catalytic converter. Last night, I went back to check under the hood and saw that my 120 amp fuse was separated (blown). I must have overlooked it because I was look for smoggy or burnt fuses. This was clear but definitely popped. Now, I have to remove the fuse box to disconnect it from inside the fuse box. I had tested the smaller fuses which some worked and other didn't using a light tester, yesterday.

Suggest you disconnect battery cables before you attempt this repair. Get back to us with result.
