With the ignition on there is likely a solenoid that combines both banks of batteries. So your refer and house battery is seeing the engine battery voltage plus the charging voltage if connected to shoreline.
IF your house battery is bad then removing the path from the engine battery may see the house battery voltage going to near zero if it is really dead.
Check your house battery voltage without the key on or shoreline connected.
If you find it to be ok, plug back into shoreline and take the measurement again, then turn the ignition switch on and take that measurement. Write them down as you go. It is easy to get derailed taking a lot of measurements.
This could be a simple automatic resetting circuit breaker not functioning. With those measurements we should be able to sort it out quickly.
