Appreciate any help.
I have a 2017 Thor Miramar with 2 6 volt batteries. They both test fine. They will charge when the engine is running but will not charge when parked and hooked up to shore power. I do keep use switch on while parked.
Two different circuits required here. One from the alternator to charge while engine is running, and the other is from the converter to charge from shore or generator. If you just have a converter, make sure it's connected. Mine (albeit old) is plugged into a wall receptacle for its 120 volts. Without knowing your system, you may have a circuit breaker specifically for the converter as well.
