my 1980 280zx is dead. i put a new battery in it and it wouldnt start after running it for three days, so i knew that the alternator was bad. i went to get a new battery and also some new battery wires and terminals since mine were going bad anyway. when i installed the battery wires and hooked up all the grounds my car was still dead. no lights no nothing, complete loss of power. i have a new alternator and i have tried to find any bad fuses but im not sure what to look for, any suggestions?? thanks
