2005 Keystone Montana 3400RL Electrical Issues

I had my 2005 Keystone Montana 3400RL 5th Wheel unplugged for a while. When I plugged it back into its 50 amp service plug only my wall outlets and water pump are working. My ceiling lights, slides, fridge, microwave, water heater, and ac are not working. All fuses and breakers are good.

    microwave, water heater and AC have no connection to the battery whatsoever.
    To start, check to see if you have power to both legs of your 50A service “inside the trailer”.


    Water heater and ducted air conditioners often need 12 volts for the control circuits.

    I suspect one leg not working.

    Check the gfci outlets to make sure they have not tripped?

    Apparently you have some dc stuff and some aC stuff working but not all of either.
    Sounds like a dead leg maybe. Otherwise it doesn’t make sense.

    Good info above. Load check your batteries (free most auto stores) as they may be compromised from being discharged.

    Good chance that you do not have full 50-amp connection to the rig.
    Are you plugging into a 50-amp receptacle or using and adapter. If you are using an adapter it could be bad.
    Another possibility is a connector on cord is bad.
