Only 1/2power

[okierver]

my family s niece has a rental travel. Trailer and only has power to the a/c microwave and gfi fault no power to any lights fridge or water pump nothing 12v or110 but the a/c and Microwave work. Checked c/b's good swapped c/b wires from the inverter c/b to the a/c circuit breaker that didn't do anything : will the inverter go bad all the way or partially any thoughts would help

You certain the 110 is only working on half the rig? Sounds like no 12v to anything which would render all items you described dead.. Did it just stop or has it been dead since she took possession? Assume you've checked the converter breaker on the AC panel? What is the battery voltage both with converter breaker on and off? Did you try google for the trailer model and a battery disconnect?

Everything was working the first nite the 2nd evening is when it stopped t

Check all GFIs. Sometimes one in a strange location will fail cause a similar problem.

First thing I would check. There may well be an outside GFI as well.

Yes, do this.

If I read the OP correctly, the main 120V items are working properly, AC and Microwave and you have power to the GFI. The breakers you changed are all related to AC with the exception of the one that supplies AC to the converter and switching that did not make a difference. My guess is that since these items worked for one night that the battery was drained during that time and is not being charged by the converter. I would check to see if there is 12V at the converter, check the reverse polarity fuses in the converter also, there should be 2 or perhaps 4 of them depending on the rating of the converter.

If the converter were working you would be able to run all the lights, fridge and pump from the 12V being supplied by the converter. This is a 12V problem,, not 120V unless there is no supply to the converter.

Check your battery voltage, that will tell you a lot.
