Has any one ran a Alternator with a internal voltage regulator?

...Additionally 1 wire setups stay hot all the time and unless you drive your car every day will kill your battery stone dead in short order.

Reviving an old thread

In the process of rewiring my 67 Barracuda (M&H harness - factory duplicate). Had a battery drain I couldn't find. It has a Powermaster alternator w/internal VR. The guy I bought the car from used the original harness which had an external voltage regulator too, only he had one wire to the alternator.

Probably my issue?
