2007 Dodge Nitro electrical issue was created by TOMMITYTOMTOM
2007 Nitro , 3.7L . Daughter's car. She called to tell me that the alternator was smoking. She knows her way around tools so I had her quickly disconnect the battery. I determined that the alternator was bad and installed a new one. After making all connections, I have a dead key. Battery is charged but no gauges, no start. Was told by a mechanic problem was likely the TIPM. (Totally integrated power module). I sent the unit off and the repair facility shipped it back at no charge stating that the problem I'm having isn't covered in their repair procedure. I've tried jumping it, nothing. Dome light work IF you manually turn them on but not through door switches. Door locks dead. Nothing comes on inside or outside the vehicle. Any thoughts ? I fix 99% of all of my car issues. Alternator was easy with 3 bolts, belt 1 plug and the charge lead. I get 12v+ to the TIPM, no blown fuses.

have you checked the body to engine grounds?? if not clip light on the body strut bolt etc then use testing end probe engine block. you shouldnt see it light if you do you have a bad ground.

All fuses in TIPM are good. No Communication to Scan tool as well. Tool gets power from data port but will not communicate. I'm suspecting ECM.
