My class C has a relay that couples the engine charging system to the house battery ONLY when the alternator is powering the rotor winding internally.
In other words it requires alternator output to connect the two systems? Is this a typical wiring scheme, rather than ignition on to connect the batteries?
Reason I ask is in alternator failure scenario I am hoping to run generator and back power the engine from the power converter.
If there is 12 volts in the chassis circuit the relay will be closed and the power will run from higher voltage to lower voltage, period, it doesn't know or care which direction.
A diode is different altogether, it would only allow current to flow in one direction.
