Try turning off the disconnect switch that disconnects the inverter from the batteries. This should show you that 120vac is NOT being passed by the inverter to allow the fridge to run. On the wfco inverter 120vac power comes into the inverter on the back and should be labeled shore power in, as well, 120vac power out should be labeled as well. With shore power off and the batteries disconnected from the inverter, it should be safe to take the romex wires out from the back of the inverter. You should be able to positively identify the romex coming from the circuit breaker panel by making sure all wires of both romex cables are separated and turning on shore power and meter both cables. The c.b. cable should be live/hot while the fridge romex should be dead. Assuming the factory did not have the romex cables reversed...then connecting them together with power off and restoring power should power up the fridge and confirm the inverter is dead. John
