Was thinking that may be a possibility, however slim I would rather try that than chase those wires down. I'll throw my Escalades battery into it after a charge and see if that works and go from there. I know it wouldn't be the first bad battery I've had that tested good in a car.It could be just a bad battery. Had one on Thursday, alternator was charging in the 12.9 to 13.2 range, swapped in a new battery as I always test with a known good battery even if the one in the car tests ok and back to normal with the good battery
