I have a 1999 Lumina that went dead in the Wal-Mart parking lot. They boosted it and I drove it to their repair bay. They put a new battery in it because they thought that was the problem. All seemed fine for a few days. The battery light went out like it should. Then, several days later, the battery light came back on, so I put another alternator on. The Batt light is still on and according to the volt meter, there is only 12.15 volts measured on the alternator and battery.
Does anyone have any idea what the problem could be?
Thanks in advance.
Rick
