Our coach engine alternator charges my batteries .
I know this because i have a separate DC Voltmeter on the house batteries & when i start/run the coach engine i see the voltage on my meter increase (matching the output of the engine alternator), turn the engine off & the voltage displayed on the meter goes DOWN, displaying the voltage contained in the batteries.
when my generator is running it also charges the house batteries (assumed coach engine is off).
I don't have less than 40 bucks tied up in these meters -
