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.
Converter is always connected to the 12v house battery and systems. Only exception would be if you have a 'storage' switch that disconnects the house battery.
Converter should produce about 13.6 volts DC whenever 120vac is available. All systems and house battery should be at 13.6 volts when plugged in. OK if the battery is low, voltage may sag a bit until charged.
