I got 50 cents says your regulator wire is open somewhere ... check the voltage right at the alternator terminal ... not the connector, but after the connector (could be broken inside the connector).
Forget underdrive pullys ... you eleminated that when you reved it up with no change .. forget a short in the output .. you short a 100+ amp alternator and your gonna have sparks, or at very least a very very hot wire somewhere. The only logical explination left that i can see, is the voltage sense wire, that tells your alternator what to put out ... if it's open and there is no signal getting to the regulator, then the alternator won't put out squat, leaving you with only battery voltage, which at full charge is around 12.6 volts.
Thats my 2 cents worth

I think we have a winner! HotRoddin, where the hell have you been for the last 4 pages??? LOL
Sounds legit to me, check into it and LET US KNOW!!!
