Chassis node power input

[Mattman]

I would think by it giving a check fuse code that you have power loss on one of the power wires going to the chassis node.

Probably a wiring problem. Start at chassis node and check for voltage on connector. If like my Kenworth it will have several power wires going to node.

I had a two broke and a couple more wires rubbed inside wire loom at chassis node. Dirt had gotten into loom and rubbed them into.

I used the exploratory method to find my problems.

It's a pain to say the least.
