2003 columbia no power outlets and no interior lights! help! please

have about 20 freightliners depending on the engine there is a wire from starter runs under the engine to fuse box above the left steer tire
had to redo the wire in the harness to tell lvd that the alt is charging
had to redo alot of oem wire harness the split loom rubs bare spots in the wiring

 

I have the same problem. Where is the low voltage protection switch located? I can jump power over in the fuse box and get power to everything so it tells me the problem is before the fuse panel on the passengers side dash.

 

In pass side wall, behind the seat. Use coin to open a small door

 

Ok, I found it and it is flashing a red light. I have restarted the truck several times and still nothing. Is it possible that I have a bad battery/batteries?

 

i see fuse links sometimes.

 

you do know there is a major fuse panel on top of the passenger side of the dash right?
