Ok. So I have a weird one. I've never seen this. My car has no charging problems at idle or around town driving, but if I get on the gas or exceed 55mph then my door ajar light and E-brake light on my cluster come on, as well as the low voltage light and my voltmeter says I'm only getting 11-12 volts. As soon as I let off the gas it goes back to normal. It all happens in an instant. It doesn't gradually drop off. It just goes 14v. BAM! 11-12v.
My car is an 83 280zx na. The alternator is about a year old and I've checked all my contacts, terminals, and connections. I'm at a loss. Any help is appreciated.
