Chassis Battery

[devild34]

I have a 2005 Georgetown by Forest River Class A RV. When storing my RV for the winter plugged in to Shore Power, does my trickle charger for the house batteries charge my chassis battery?

It would be your converter if it did. Check chassis battery voltage before and after shore power applied. If it is charging from shore power the voltage will increase just like the coach batteries will.

That's a good question on my old class A there was an idolator that kept current from flowing from the house batteries to the chassis battery unless a monetary switch on the dash was pushed. What you try is use a meter measure the voltage at the house batteries when fully charge and then check the chassis battery if they read the same I would say its charging.

That "isolator" is a relay that energized via a "momentary" switch on the dash for emergency (AUX) starting from the coach batteries when the chassis battery was low. That same relay is also the relay that automatically energizes for cross charging (chassis to coach via alternator/coach to chassis via converter) the batteries if the coach has that capability. The OP's 2005 Georgetown may or may not have a battery control center to provide that capability. We did offer suggestions to find out though.
