I talked to my work and there is a DC clamp meter I can bring home to try troubleshooting this. I wont be home until mid next week so I can put a plan together on things to test.
- Clamp the positive and negative lead on both truck batteries with the camper plugged in and unplugged. Ideally both readings should be 0.
- Clamp each wire on the 6 pin wiring harness on the truck side while plugged in and unplugged. Even both 8 gauge + and - wires.
Any other suggestions on what I should try to use the DC amp clamp on? Or something else I should try doing to solve this problem?
Thanks for the help guys
