Ok guys, like many of you I just did my alternator upgrade on my stock 76 280z for a new 280zx alternator along with voltage regulator removal and wire solder..here is my question I know on new cars to see if the alternator is working , you removed one of the batt + or - and the cars stays running, so I did the same thing on my car and as soon I removed one of these the car turned off, is it normal on these old all cars???
