Paul,

One additional thought....if you can, try to develop an understanding of the systems and how different switch positions affect the system. Liberty powers the inverters and the battery chargers on two different circuits.

The house battery charger circuits are not to be confused with the bus chassis battery charger. The two sets of batteries are not joined.

All 24V house circuits run off the house batteries such as lights, fans, Webasto, etc. These items include the things you noticed failing to function properly. You also run certain circuits through the inverters when the shore power or generator is not supplying power such as the refrig, the TVs, the outlets, etc. To maintain those batteries they should be charged any time the bus is connected to shore power or the generator is running. When the bus engine is running they are being charged automatically by the bus alternator.

It will help you a lot if you understand the system and know how to monitor the house voltages. Liberty can walk you through that.

My guess is that if you were running the TVs some AC units and the refrig you were getting shore power into the coach, but the battery charging circuits were off. With those back on everything should be OK.
