Year.... make.... model of your coach?
If you screwed something up changing your house batteries, it would not effect your AC appliances (other than something connected to the Inverter).
DC only powers coach lights, radio, etc. Turning off an Inverter breaker should have no impact on coach lights. Only the Use/Store set in "Store" position would keep the lights from coming on.
What happens when you are on generator power? If you have AC power on your generator, it could be your transfer switch if everything else on the shore power side is ok.
Are you sure you have power at the receptacle where you are plugged into shore power?
