Electrical Help Please

i have a 2006 Fleetwood Bounder diesel that only charges the house batteries on shorepower. I have a Big Boy Battery Isolator Relay and a Battery Control Center(BCC) #F73-1042. I'v e been told there is a bad solenoid in the BCC behind the fuse board but the schematics show no solenoid in there and I don't want to take the BCC apart if I don't have to. Need help where to look? Is the Big Boy only there to connect all batteries when the AUX Start button is pushed? Any help is appreciated

  • My RV did not come with starter battery charging so I added a Trik-L-Star.
  • why not the BBC model number
    either from the schematic on the inside of the cover
    or from the number on the circuit board

    post that here

    we can help you look up the functions for that model
  • May want to look in a "Echo Charger" a device that allows charging of the chassis battery/batteries while on shore power.
  • The batter control center may have a charge function from shore power, however many do not. Look on the circuit board for a fuse marked BD if equipped would energize a charge relay. That is a bi-directional relay.

    I would assume that's why there is a Battery Control Center
