1989 Mustang-external voltage regulator
I got a 89 gt 5.0 reading repair manual, and was wondering if it had one? for some reason when I turn my headlights on or hit the brakes the amps go down a bit on my car. I was wondering if this maybe have something to do with it? I checked out all wiring new alter. new battery. Where is this located at if it has one, and if so you think this could have something to do with it?
