Good to know. Never had an external reg.
Newb question: Is there a standard RPM I should get my alt measured at? I also have a Tenney alt and my mechanic said it was doing 254 amps, 15.6 volts, but didn't specify at what RPM. When I bought it he said it would be a 270 amp alt and in another phone conversation mentioned 300 amps. It was $300. I had some issues getting my alt. I was initially sent an alt that was faulty - the bushings were rubbing against the case. I sent it back and he repaired it and sent it back again to me. It's now in and working though.
