My alternator is not charging the battery for some reason. I switched out alternators and still no charging. I have not had the alternator tested but I can't believe I would have two bad alternators. Does anyone have a diagram of the charging circuit and the electronic control unit which is what I think controls when the alternator kicking in. The two trigger wires that plug into the alternator are completely dead after testing them with a power probe with the motor running. I see someone posted a manual for a 2009 LT but I have a 2009 turbo so it's different. Other than the charging problem, the motor runs fine. I have not pulled off the positive battery terminal while the motor is running, maybe I should. The battery light does come on after a short test drive. After the short drive, the battery voltage was 12.4 and started at 13.4. Or any other ideas?
thanks
