So, I was running my 88 Fifth Avenue, and I have one of those FM transmitters through the cigarette lighter. Its reading a voltage at 10.5 or so while running, but the guage on the dash is reading perfectly center, just as always.
I don't understand, and I don't know what to trust. I'm inclined to trust the guage cluster because I had to crank the car for a little while (must've flooded the carb by accident a bit), and I saw it go down, and then returned to center within a bit of driving.
Update: Ran the multimeter on the battery... while idling, it eventually got to 12.45 or so. When I hit the gas, it actually went downnin voltage. I'm going to bench test the alternator, as I only replaced it 2 years ago, but the car sat for a long time. If that's good, then I'll try new battery cables. Battery and voltage regulator were recently replaced, and the problem started just a little bit before I replaced both of those components.
