Generator Output

Driving my car around at dusk, I've turned on the headlights and the ammeter goes from about +10amp to -5amp. I can rev the engine but it doesn't go positive so I'm assuming I'm draining battery. Is there an adjustment I should make so that this doesn't happen or something in the generator I should check?

Re: Generator Output


Most if not all of our old cars have whats called a third brush in the generator, you can loosen a screw and advance the brush(one way or the other) to regulate your voltage...The third brush is pictured in most of our wiring diagrams in the tech page.

Thanks, I did adjust the third brush and this did the trick!
