Fine Tuning a 360 Magnum with a Brawler "Double Pumper"

I’ll check voltage again in a minute, I’m going to go pull a plug and take a peak. I really only get alternator issues at idle, once I’m driving it’s fine. I notice the headlights and dash dim and the voltage gauge drops down but when I’m moving it’s where it normally is.
That's normal Chrysler electrical bullcrappary.
