Pop up lights question

First off, I'm going to admit I don't know very much about pop ups or electrical systems. The lights in my pop up (interior lights and outside night light) work when the camper is plugged into my truck for towing but do not work when plugged into a shoreline or when trying to run off battery power. I checked the fuses and they don't appear blown. If I bang on the fuse box, the lights and the CO2 detector flicker on momentarily. I've checked for loose wires but I don't see any. Any ideas?

Sounds like you have either a loose or a corroded connection, if there are no blown fuses. You may have to remove the power converter, and check the wiring going to it carefully. Also, a wire could have gotten pinched where the lift mechanism goes up and down, and the wire inside the plastic sheathing could be broken. Had that happen on my94 Coleman pop up before. Hope this helps! Randy

Search for how to troubleshoot a wfco converter. Long story short, your converter is not working.

Do you have a voltmeter? It seems that you have 12V at the camper from your truck but not 12V power from the camper's battery or converter. If you disconnected the battery and measured the volts across the terminals...anything less than 11.5V is about dead. With the camper plugged into 120V, the converter should be outputting about 13.5V measured across the battery leads.
