Sheeterangel Report post Posted May 19, 2015 Can someone please tell me where the house battery cutoff is on a 2003 Fleetwood Discovery? It says to cut them off when you are on shore power so they will charge. Ours is steady discharging and when we cut off the aux switch when we are on shore power, everything goes off.

dickandlois Report post Posted May 19, 2015 Sheeterangle, Welcome to the FMCA Forum! Could you post the make and model of you inverter / charger for the group? And any information on the monitor and control panel for the inverter / charger. The charge and inverter circuits are often controlled by this unit. Many of the models have 2 - 110volt circuit breakers that power circuits in the coach. So if you find a circuit breaker in the main AC power panel - it most likely will turn off the unit, but also power off the 2 circuits mentioned. Rich.

wolfe10 Report post Posted May 19, 2015 Sounds like your is wired backwards. The chassis battery may have a separate cut-off switch, and if your coach does not have some means of charging from shore power (many do not), disconnecting it while camped can slow down its discharge rate. The house battery, whose cut-off switch is generally near the entrance door must be left on for 12 VDC functions in the coach to work. Your inverter/charger WILL keep the house battery bank charged when you are on shore power or the generator is on. Many have added a separate small smart charger or "power share device" such as a Xantrex Echo Charger to keep the chassis battery charged from shore power.

kaypsmith Report post Posted May 19, 2015 Thanks Brett for responding to this one. I have been using motorhomes for nearly 30 years, and have never known anything about disconnecting house batteries needing to be disconnected while on shore power. Since the lights, even the camper style fridge, and water heater depend on 12 volts. With the batteries disconnected, none of these and in some cases other devices would not work, in addition to the battery converter not being able to charge the batteries.
