'69 Firebird 400 - Alternator heats up when the engine is off and the battery is hooked up.
Anyone have a clue as to what may be hooked up wrong? There is a new "Painless" wiring harness, hooked up as instructed.

couldnt be a faulty ground wire or poor ground connection could it...

Your best bet is to have it looked at by a shop that rebuilds Alternators. Even if it needs to be rebuilt it shouldnt cost that much. I had mine rebuilt and upgraded to 100 AMPS and it only cost $80.00

I would suggest that one or both of the diode sets in the alternator is shorted.

you have one of thee problems either short in alternator bad regulator IE not shutting off or bad starter solenoid . you did not say if you replaced wiring harness trying to fix problem or if it started after you replaced it , remove pos battery clamp put meter from clamp to battery unless you have an assecory like stereo with clock or memory it should show zero disconnect regulator if it shows 12 volts and see if it drops to 0 if it doesn't replace it some time people have swapped out alt. with external regulator and put in one with internal regulator with out changing some wiring this will cause things to get hot
