The ELX-30 has 2 breakers and 4 fuses on the front panel. There is also a reset hidden behind the battery box which I believe has to do with the generator. The 4 fuses are all good. With the camper plugged into 120v., the 'wall socket' DOES operate at 120v., so as suggested above, there is 'pass-thru'. That's good news. Everything else that runs from the batteries still work. But replacement of the ELX is in order. In the meantime, I'll carry a battery charger and plug-in overnight at campgrounds. I have not started the generator to see whether I get 120v., but it seems that should work. TM...
