Voltage regulator upgrade? Keep frying voltage regulators with swap

FYI - unplugging the voltage regulator didn't help. I had to cut the 12v to the alternator for it to quit charging.

This MEANS one of two things:

1....either this alternator DOES HAVE an internal regulator

2...or there is some sort of field short or wiring problem that is causing the regulator to be essentially ineffective

This also means.........

1...that if internally regulator, whatever regulators you are buying are not needed and incorrect

2...that in any case the external regulator is NOT the root cause of this problem, even though it may be failing. The "actual" problem is the cause of the regulator failing.
