Cab battery advice please

[Rodders1234]

Being new to MH I am not sure whether my cab battery is being charged when I am on EHU? P.s. I know its not being charged from the solar panels. Help appreciated, thanks.

To be sure.... If you have a volt/multimeter connect to the battery and note voltage.
Connect hookup and recheck voltage.
If it increases its being charged on hookup, if not then it isn't.
