So the testarossa is done over heating. But now, I take it out, brand new battery, and it dies once the car is stopped and turned off. Alternator? Sure sounds like it but wanted to check here first. Thanks
charge battery to see if you can start car. No could be dead cell in new battery. Yes points to alternator. once running 1st test is if you get 13.8+volts from battery terminals implys alternator could be doing its job. If no check alternator. If yes and battery dies again your alt many not be putting out enough juice and it needs a real bench test.
