Toyota Repair: 1987 Supra Turbo Blowing AM2 Fuse, electrical wiring diagram, wire harness

Question
I was driving and the Supra lost all power and would not restart.  We towed it home.  The AM2 fuse was blown.  Replaced it and now it blows when we turn the ignition to the start position.  Any recommendations?

Answer
Try disconnecting the electrical connectors from the starter and see if the fuse stays intact, the starter may be drawing too much current, does the engine turn over normally with the starter? I don't have an electrical wiring diagram for an 1988 supra so I hope this helps a little, also check the wire harness to the alternator for signs of having burned or somehow grounded itself.
