MagnumR01 Report post Posted April 9, 2023 I need a wiring diagram or help knowing about a no start no air heater on 01 Renegade sedona on the Magnum R series chassis. Cat 3126 B with Allison. No power to chassis fuse and relay. But when I get the ignition wire going into it jumped to power auto tranny control comes on to N. The air heater comes on and she will run. I just don't know where this 14ga ignition wire comes from that goes into the chassis fuses by the battery bank. I assume it's shorted somewhere upstream.

f430040 Report post Posted May 5, 2023 It is more likely OPEN somewhere upstream, not shorted. If it was shorted, you couldn’t jump power to it to make it work. Sorry, I can’t help you with a diagram. Share this post Link to post Share on other sites
