One additional question: Is converter out of charging circuit when engine or the generator is running??? If so, are bad fuses still a possibility?
No and Yes.
The converter only converts 120v AC to 12v DC, therefore charging the batteries or running 12v systems. That means it only works when you have shore power or genny.
The alternator from the engine provides 12(+)v to the batteries. No converter involved. That is why batteries are charged when driving (even if converter is off or dead).
