Make sure converter charger power plug is plugged into a live 120volt AC outlet on the power panel. Test for 13.6 volt output of converter/charger at it's terminals with a voltmeter/multimeter set on 20 volts DC when connected to shore power. Check tightness of connections of thick wires at terminals on converter/charger that go to the house battery. Most converter chargers have allen head set screws that bite into the bare ends of these wires. Check connections at other end where these wires connect to the battery. Make sure that all wires are connected at battery properly. It is easy to forget to connect a wire when replacing house batteries. If flipping of circuit breakers and checking of all fuses doesn't work it is probable that your converter/charger is not working. It is easy to replace and connect a new converter charger. The PD9245 from Progressive Dynamics will have modern fast charge and maintenance charge levels and a monitor thingy that shows what it is doing. Make sure that all battery connections are clean and tight. Check electrolyte levels in battery cells. Check voltage of batteries. It's possible that one or both batteries are dead from lack of charging.
