So I have a 78 280z that I rescued from an abusive home a few months ago. Didn't run at all when I got it, but thats since changed. I've been test driving it and it died on me the other day. It led me to believe I have charging issues. I took a look at the alternator and its a recent upgrade from a 81 NA 280zx. The alternator itself is only putting out 12.3v when idling at 1300rpm. The "L" cable is only putting out roughly 11.8v into the alternator. When I swap this with a hot wire from my battery thats putting out 12.3v, the alternator starts making unbearable noises. From what I've read online, this zx alternator should be putting out ~14v constantly, however I've never seen above 12.5. I took it off and took it to autozone where they tested it twice and said it was fine. Battery is also brand new, bought it at most a month ago. I'm stuck, because the longer the car seems to be on, the more it seems to be draining. And after 15-20 minutes it will just be too drained to run and will die.
