house batteries go dead while driving

my house batteries went dead traveling from Maine to Florida. I checked the voltage at coach battery, with engine running, at 14 volts, at house batteries 12 volts. If I go into motorhome, and toggle the use/store switch from use, to store, then back to use, I get 14 volts to house batteries. ?????

    1. When using the RV you NEVER have the Coach or Battery disconnect OFF. WHY would you have it OFF? This may not be the problem
    2. From what you state, your Battery disconnect solenoid is sticking. Replace it.
    3. You do not state what disconnect system you have. Does your system have a ON indicator light to let you know when it is OFF or ON?
    4. Some Motorhomes require that disconnect solenoid to be ON to transmit engine voltage to the coach batteries. Doug
