For the installation to work properly there really aren't any choices in the wiring configuration. The Balmar installation instruction indicates that the regulator itself gets powered from ignition,...

I don't believe there was any control panel voltmeter in a Roadtrek before the later 2016-2017 production. For owners predating the voltmeter inclusion, how would they have any way of determining the...

Regardless of the trigger that the BMS employs, once the battery shuts down, it can't awaken itself to accept recharging without some stimulus to reopen the charge path.

No question that the Nations alternator needs a battery load to deliver power but that's because any modern alternator, needs this. But I think it has nothing to do with excitation, per se, and more...

The AGM is not supplied to excite the alternator. When the BMS shuts down the battery, it can't restart and reopen the charge and discharge ports by itself. Early Etreks ran into the problem that...
