Hello. I have a 2012 Jeep Grand Cherokee that isn't charging. Replaced battery, alternator, and pcm. Load tested all associated wiring.. no 12v output at c2 from pcm. Any ideas? Mechanic's Assistant: Have you checked all the fuses? Do you have a wiring diagram? All fuses at TIPM are good. Checked all wiring against a mopar wiring diagram
According to Google, the battery in the pic 05033394AB - Battery - Europe, Export, Middle East - is no longer available and was replaced by part number BE0H7800AB. BE0H7800AB is listed as Group Size H7 - 80AH/800CCA - Polarity 0 (positive terminal on the right side) - Dimensions 315x175x190 - AGM. G. Galaxy Discussion starter.
Once both batteries were installed the Jeep started right up. The main battery increased to 12.9 volts within 5 minutes of the vehicle running, the auxiliary battery dropped to 12.2 volts in that time. Within 10 minutes the jeep began to sputter, the main battery was 13+ volts the auxiliary battery dropped to under 6 volts.
