As far as shore power and engine alternator charging, the converter/charger puts out 55 amps while the engine alternator puts out 80 amps. So the engine charges the batteries more quickly.
Under shore power, the power goes to the coach batteries first and then the chassis battery. The reverse when using the engine alternator.
correct,...but mine clicked when it hit 13.4, as I was standing there... it was at 13.1 for an hour....also, at the same time... the monitor reads higher than the meter on the battery direct

and also correct,... the shore power would not charge the battery's till I pre charged them with a separate charger...
