Charging issues.

[Tdbengry]

I’ve asked this before and didn’t quite get a clear answer, so here we go again I installed and wired a race mate water pump alternator combo in my truck I unplugged the external Voltage regulator as the new one has an exciter. After unplugging the external voltage regulator my battery dies in about a week seeming like there is a parasitic draw I’m curious If I can do the voltage regulator delete and re-wire for the internally regulated alternator and have it work the same on my combo alternator.
