I understand. There is no room. I need you to check a couple things dealing with the alt before we move to the pcm.
First, check the voltage between the alt B+ terminal and the battery Pos + terminal. Start the engine. Is the voltage above 0.4 volts? If it is, repair the B+ wire between the alt and the battery for high resistance. I believe that wire is a fuseable link and may have gone bad when the wires were crossed.
If all is okay there, do the following:
Now, we need to make sure there has been no damage to the alt ground. I need you to check for voltage between the alt case and the ground on the battery. Is the voltage greater than 0.1 volt? If it is, you need to repair the alternator ground for high resistance (alt case to battery ground side).
Please be careful when the engine is running to keep clear of belts and any moving parts. Let me know what you find. Also, I know this is going to be difficult on this car, but I'm thinking a wire melted down.
Let me know what you find.
PS: Check the power distribution box under the hood to make sure there are no blown fuses there too.
