A few more bits of info would help us help you
! (You show Pathfinder as your coach in profile.). What year and model? Is it only on Generator that electrical is acting up on those items? Or when plugged in, do you also have a problem? IF you had a heavy load and the stars aligned for and a few items kicked in 'surge' wise at ehe sometime. Do you have any electricity flowing to any of your 120 outlets or loads?
It's possible you blew a Bus Fuse. These are on some CC's, back in, or in a compartment above, the battery bay. Also some coaches electricity flow thru the Inverter, and sometimes a 'reset' of the Inverter will allow Pass Thru of juice downstream into the coach.
More info, would allow more finite help
