Powertron rm 300d model help urgent

[Mysticaxe]

Powertron rm 300d model. This thing keeps switching the breaker buttons. I had even shaped a breaker around to see if it was a faulty one but it's the dame position. I thought it was an issue to the Coleman heater I also posted about. When I reset the breaker the lights of the rv interior will flicker before the breaker flips. I may have to just gut this converter for a newer onenifni cannot get it to work

I have about a week tot get this working before my trip

I would say that if the lights flicker and then the breaker button pops, ITS DOING ITS JOB, and you need to find the short. Examine the panel for loose connections or something shorting, especially where the wires exit the panel box, but don't blame the panel for a short elsewhere in the camper.

Got the short fixed out but still having issues with the fan for the heater not wanting to turn on. As before I couldn't find where the short was going to. All the wires looked fine smd nothing was out of place. My dad took a look and fixed that issue but now I'm struggling with having no heat. The pilot light won't stay lit. It will only light and stay lit when I press down on the pilot light Gas knob.

So currently after charging the batteries I have come across another issue. So I thought we had fixed the circuit breaker issue but when I watched the wires to the battiees the lights wouldn't come on. As I had red to positive black to negative and the. A set of multiple white cords on one ring end to attach to the bolt. Yet when I have the white with the positive wires. No lights will turn on. Yet when on negative with black. Lights turn on but the circuit breaker flips. My father who is a mechanic has troubles trying to find the issue. Of why it keeps tripping. I know it's supposed to but we cannot find where the issue comes from.
