Question electric humming when it's not plugged in

My husband drained the water from our 65 Caravan and all went well. Then hours later the electric started humming even though it wasn't plugged into an outlet. He finally disconnected a wire or something. Any ideas? I hope he didn't do permanent damage to something. I posted before that we had a humming when we connected it to an extension cord for power in our driveway.

Please help. We are trying to get it winterized and hope to have it ready to go in the spring.

Thank you!

Ann Dunham

What tune was it humming?

Ann,
I think you may have had two different items involved here. The humming you hear when plugged into "shore" power was most likely the uni-volt ( charger/converter) . The humming you were hearing after it was disconnected and the water tank emptied could have been caused by the water pump still trying to pump water that wasn' there. There should be switch on the control panel to turn it on or off.

I hate to admit that I don't even know where the control panel is How can we make the pump not try to pump water that isn't there? I am afraid that the pump or electric is going to burn itself out. I just bought the trailer in August. We are in NY and it used to live in La. I don't think they had to winterize it down there. Also the stuff I bought to pour in the drains said to put it in the water tank too. That can't be right!

Winterizing is a necessity

Ann,
I would not put the antifreeze in the water tank, it will be a pain to get out. Here is a link to Winterizing . But basically you drain everything, put a bypass on the water heater, and pump the piping system full of RV antifreeze and pour a little down the drains to protect the traps. IIRC on a AS of your vintage you have to disconect the pump too as part of the winterizing process. Hopefully someone with a similar vintage to yours will be able to give more specfic directions. As far as the location of the control panel.... On my 1975 it is over the galley, on my buddies 68 it is over the fridge in it's own little cabinet.

In 65 the water pump switch looks like a home light switch. There is normally not a label to tell you it is the switch for the pump Depending on the exact model (safari, globetrotter, caravel, etc) you have it could be in the cabinet over the refer, or on the wall near the kitchen sink.
