Hi, Trying to help, but need more info

What year, and model camper do you have?

Do you know the brand of power converter?

It may be that the power converter has stopped working, the battery got drained down and the converter will not recharge it. The battery might be OK. You can take the battery to NAPA autoparts and maybe Advance and they can do a free battery test, it will tell if the battery is bad or just deeply discharged.

Power converters come in lots of different sizes and shapes. Many times you can keep the fuses, circuit breakers and the main housing and just change the converter controller inside and reuse the rest. Other times the whole thing has to be changed. We can help better if we know what you have. Picture also help greatly.

Do you have a voltmeter and know how to use it? By doing a voltage check at the battery with the shore power plugged in, you can tell if the converter is putting out anything.

There is also a fuse or self resetting circuit breaker between the power converter and the battery that may be bad, pending the vintage and type of the converter, some must have a battery installed others work without a battery.

With the shore power off, no 120 VAC plugged in. You can try this, plug the 7 wire cable into the truck with the truck running. Then see if the lights in the camper are any brighter then without the truck plugged in. If they get brighter by any amount, then the fuse/circuit breaker and the power converter are still working. If there is no change, report that back too.

Hope this helps

John
