Electrical Reg 120v and GCFI

[Whited Haired PaPa G]

I have a 2019 Montana 5th wheel 362rd. I'm having electrical issues with the regular 120v some GCFI outlets. The GCFI switch in the bathroom has been checked and reset all the breaker switches and fuses are good. All the lights inside and outside kitchen work. I have some 120v and GCFI outlets that are not working. I have checked them all. I'm new to RV'ing and confused what's causing the problem or where else to look.

The lights are all 12vdc LED and run from your batteries or converter.
The 130vac system has two legs each on its own 50A circuit breaker.
Are all the probem receptacles on the same leg?

When you say “all the breaker switches and fuses are good.” what do you mean. Do you have 120 vac at the load side of all the circuit breakers? Fuses are for 12 vdc.

As Daryles noted there are two 120 vac hot legs. There have been a number of occasions where someone has lost power to one of those legs for one reason or another. That would result in some 120 vac outlets and appliances working and some not working.

How many GFCIs master units did you find? There should be one on the main bedroom and another near the kitchen/second bath. I doubt the bedroom GFCI circuit also serves the kitchen. Too much load and distance.

The next step is to use a VOM and measure the voltage in and out of the GFCI and the follow the wiring to downstream outlets. The bedroom feeds the shower, bedroom wall, pass through, and maybe the outside outlet. The kitchen/second bath (I am guessing it is in the 2nd bathroom) will likely feed the bath, kitchen and ??
