I have a small issue and was hoping someone could help me. I have a 28" trailer hooked up to my truck through a 7-pt Bargman.

The initial problem was the 30-amp fuse blowing that feeds the running lights on trailer and truck. I seem to have fixed that by going through the wiring and regrounding the factory wire harness and cleaning all terminals on the 7-pt Bargman (truck and trailer ends).

My last challenge is the interior lights. They do not work and seem to be wired to the "battery charge" section of the 7-pt Bargman. I have used a test light and there appears to be no power going through that wire. When tracing it back to the engine bay there is a Pollak circuit breaker in-line that IS getting power from an ignition switch on the passenger side of the engine bay but not getting through the circuit breaker. I bypassed the breaker and now have power to the midpoint of the pick up truck but NOT at the 7-pt truck plug.

I'm assumming this wire is a "hot" lead only when the ignition is on and it would be split to charge the trailer "breakaway" battery as well as supply power to the trailer interior lights.

Is there another fuse in-line between the circuit breaker/factory harness and the 7-pt plug that I'm missing?

Why wouldn't I just wire straight from the battery positive (with a fuse) to power the interior lights?

Thank You.
