My ‘02 2500 5.9 gasser has no power at the 12v line at hitch. I’ve got power at the trailer brake plug in cab, and both the 40A fuse and relay in PDC are good (new fuse and I’ve plugged the known working blower relay in the trailer relay slot to check).
I suck at wiring, but have checked that. Are there any other fuses, or are there any common failure points along the line from PDC to hitch plug?
Previous owner did add amp and 700w power inverter in cab, but the power from amp is an added fused line at PDC lug-I don’t know if the trailer 12v line goes in the cab for that to matter.
