Inverter
If the inverter has a transfer switch like mine, and requires the 12V for operation, there could be no power to this 115V AC circuit from shore or generator power. The inverter requires 12V for both the straight through 115V connection AND the inverter operation 115V. Check the 12V to the inverter and if it is OK (big fat 8 or 10 gauge wire), the the inverter is probably at fault. 12V is used for the control circuitry inside the inverter and is responsible for connecting either source of power Shore or inverted.
