So, we just bought this MH and I am trying to understand the 12V Coach/Chassis power systems. Does not seem as the coach batteries are being charged while the MH is being driven. Normal?
If we run the generator in the evening for a couple of hours the 12V system then works OK until the voltage drops below some point like 11.9 V and the Coach battery disconnect then goes off. (This is after a night of no 12V use and a few hours of early morning limited 12V use. Turning on the ignition and running the engine will bring it back, but not charge the coach batteries. Does this seem correct? I'm also not sure if those coach batteries get charged while plugged into shore power. We spend several hours on the road and when we stop, turning off the engine, the 12V coach power goes out.
Thanks for any insight into this. It just seems that those coach batteries should be getting charged while driving.
