Charge Line on Tow Vehicle Not Working

[Daddy_Bear]

I have a 2007 Chevy Silverado. Everything on the wiring harness works perfectly except the "Charge Line". It is factory wired and worked last year. I have tested the female plug on the truck and everything works except the charge/power line. Does anyone know if theres a fuse anywhere on the truck that would kill the charge line if the fuse was blown?

Thanks

I had the NBS 2007 Silverado. If I remember correctly, I had to connect the charge wire to stud #1, and supply my own 40a fuse. If you have all that, I believe the truck has to be in tow/haul mode or the lights have to be fully on (not just the DRLs) for that line to be energized.

Don't know about GM but Ford has one under the hood. Check in the owners manual and there should be a description of the location of the fuse box and a sketch showing the location of the fuse and what it controls.

In the fuse box under the hood, there is a 40A fuse labeled "Stud #1" at least on the "Classic" models. Not sure if it's the same on the 2007-2013 body style, but worth a look.
