Gene, did you check all 6 diodes in the rectifier, as well as the three in the diode trio (or replace it with a new one)?

When you get it going again, connect the #2 terminal over to the large output stud, and the #1 terminal to the ignition switch, using a diode, a resistor or an "idiot light" in that lead, to prevent a re-occurrance of the problem you are now having, in the future.

(Without a resistor, a diode, or an "idiot lamp" in the "excite circuit, excessive current can backfeed out of the alternator through the #1 terminal, under certain conditions, destroying the regulator and/or the diode trio.)
