[QUOTE=wredman;52481]I assume the house can not drain the chassis battery?
I also assume the engine can charge the house batteries
If I drain the house batteries, I would start the engine with the chassis battery, let run a few minutes, and then start the generator with the charging house batteries and alternator power being supplied. Then shut off the engine an let the gen continue charging. Is this how it works?[/QUOTE
In the Axis the BIRD and Trombetta separate the house and chassis batteries so that running down the house batteries does not also discharge the chassis battery and leave you without the ability to start your engine. When the engine is started or the generator is turned on or the coach is plugged into shore power, the BIRD opens the Trombetta to charge both the house and chassis batteries at the same time.
So yes, if you drain your house batteries below what will start the generator, you can start the engine and wait a few minutes to put a charge on the house batteries and then start the generator.
