I am helping a friend with a 80 280ZX. He put a new alternator in and still seems to have a problem. When I pull the neg. off the bat. the car dies. One parts store said this car will do that. I don't think that he is right. help!!
bob, ihave a 1980 as well and mine does run with the negative off, being a parts store manager i can tell you that although this may not be good for the alternator, this vehicle should run solely off the alternator, if it's functioning properly. good luck to you buddy.
