get a 10SI (or 12SI, higher output), it has an internal regulator. To make it work all you have to do is: At the regulator, jump terminal f to 4 and 2 to 3.
At the alternator use the wire that went to "F" and plug it into terminal 1. The wire that went to "R", plug into terminal 2. That's it. You will still have the idiot lite, regulation at the battery, where it belongs, and no more mechanical regulator issues. For replacement, get a 10SI from anywhere. \
