I drove several hundred miles today with the refrigerator on, and each pit stop I made, I checked the house battery voltages. The voltage slowly dropped from 13 to 12.6, to 12.1, to 11.x, which was flashing red on the xantrex panel. Should the engine alternator be charging the house batteries while under way ? I could barely get the generator started, but once I did, the house batteries were reading 13.x volts again. After driving with generator running, the house batteries are still reading 12.7.
