My symptoms were: engine alternator would charge the house batteries but the generator and shore line would not. I check the converter/charger output and it was 13.6 volts. Pulled the positive lead from the converter charger off the house battery - 1.2 volts. 60 amp circuit breaker in the battery compartment was not tripped. I asked Thor to send me a 12 volt circuit diagram. The circuit diagram is a complicated mess, but blowing it up, I was able to see a relay in the charging circuit. I pulled the relay and drove to my RV dealer and had them check it -bad. Came home with a new $69.95 relay. Everything works as it should.
