1. Check the A/C breakers, usually in the same panel as the D/C fuses. Also check the outlet that supplies the inverter. Quick, safe, and easy way ... plug a night lite into the outlet that powers the inverter. If there is power to the outlet, check for a reset button on the inverter. Also check any GFI'd outlets for a tripped condition. Quite often the bathroom outlet also wires to the outside outlets, and maybe even the utility ones in the basement too. Even if your battery is stone cold dead, you should be able to find 12v d.c. at the battery terminals. Another way to check your inverter is to turn your r/v radio on to an a.m. station, if you lift off the neg. battery terminal, the radio will sound like an orbital sander. Even a dead battery will act as a condenser "noise choke in C.B. slang" for the a/c signal of the "working" inverter.
2. Check to see if your rig has a battery cut off switch,(usually bright red, bulkhead mounted, and near the battery) and check that it in the operate position. From personal experience, if it is the plastic key type, set it "off or on", then remove the key and tether it to the immediate area with weatherproof zip ties or lanyard, so that it doesn't wander.
3. Remove the battery from any load, and charge it overnight, after making sure that the cells are full of distilled water. Leave the caps off while charging at 3 amps., and no smoking near the battery. If it holds a charge, have it stress tested at your local auto supply store. Remember to kill power to the inverter while the battery is out of the circuit.
Good luck, hope this helps!
