Dropped motor in recently, fighting electrical gremlins.
Truck was arc’d with a battery cable.....Battery light stays on when truck is off. When truck is cranked battery light goes away. Did have to reprogram a new TCM due to arc.. New alternator. New batteries. Checked all grounds. Truck cranks runs good, but is stuck in park. Trans freshly restacked. Also had a glow plug 8 code that has been cleared and gone.
From Tech2:
P2510- engine control ignition relay feedback circuit
U1301- class 2 communication circuit high
Any ideas on how to approach this? I’m not sure if there is a chaffed wire somewhere or if maybe I have a bad ecm from the arc? I put a multimeter on the fuses and I can’t find any parasitic draws.
