I killed my 64 Dart GT Convertible.

Something I should make more clear: Everything was fine until I created a spark at the fuse block, at which point everything went dead. So it can't be that some connection is loose or some wire not connected, right? It's got to be that I fried something. Doesn't look like I'll be enjoying the sun tomorrow--I'll be stuck in the garage trying to figure it out. Damn.
