Engine: V6 2.5L Duratec
I bought a remanufactured alternator (130 AMP) today from Autozone. Before leaving they ran it through the tester and it came out good. I brought it to my mechanic, he installed it. The battery was COMPLETELY drained, I mean so drained the gear shifter would not unlock from Park. Ok after about 3 hours he got the new alternator in, charged the battery for 15 mins. The car started, the battery light is not on, but he is only showing 12V at the battery. He says it is not charging the battery. Is it possible that the battery needs to be charged longer? or maybe I drained it too many times? Because I dont want him to have to charge another 3 hours of labor for another alternator. The thing that gets me is the alternator passed at the store. Tell me what you think.
