Chassis Battery Charging

[davidbrady]

Hi Chuck,

I'm trying to recall the converters out there that use 12VDC inverters. The big guys all use 24VDC inverters an most likely the Trace SW pure sinewave series. My Vantare uses the SW4024 and I think your Marathon does too. This means we have a 24V house battery bank than can be used to jump the S60 in the event of dead chassis batteries. My Vantare has a button on the dash to momentarily connect the house to chassis batteries. I also have a 24V Guest charger which is available to charge the chassis batteries. The Guest charger is plugged into a 120VAC house receptacle that's relay controlled by the ignition key. When the key is off the Guest 120VAC receptacle gets power, but only if I don't have that particular load pruned. I'd look again, but I'm pretty sure you should have a 24VDC house system that should be able to jump the chassis batteries. You should definitely wire in a 24V chassis battery charger. Guest makes on as does Xantrex and there are others.
