You mentioned a rebuilt Delco 10 SI?? From what I am reading, the voltage regulator is shorted--producing all the voltage & amperage that the alternator can put out. I have rebuilt over 50 of these alternators, & when they require a new voltage regulator, the critical time for failure of a new reg. is right after initial start-up [usually 2 or 3 minutes]. I have had 2 or 3 regulators fail upon start-up -- 2 from shorting [maximum charge] & 1 from going open [no charge]. 1 other thing to check---after disconnecting the wire to the #2 terminal on the alternator, try connecting a jumper wire from the battery + terminal to the terminal on the alternator which reads battery voltage --- #2 [currently has a wire connected to the hot terminal of the alternator].
