Hello Scotty. I have a question about my 1996 Nissan Maxima. Idk if it's the alternator that needs to be replaced or what. But I had went to pep boys to get my battery tested because my car has been sitting in the driveway for 8 months. & they said my battery is fine & just recharged it for me I put the battery bak in the car & it started like a champ. Than the next day I tried to start it & it didn't start no lights no sound nothing like it just died over night?! I'm this close to losing my witts please help!!

get the alternator load tested, auto zones do that free. if not that, either battery is shot or you have a dead short in the electronics:
