Water pump possessed?

[Buddy W.]

Water pump doing it's job correctly. When tap opened pump comes on and when tap closed up stops when pressures up. Problem is can't turn switch off! Have tried every switch (sinks, toilet & wet bay) switch lights will not go off and can not turn pump off. Any ideas where to start?

All of your water pump switches are wired to a controller that actually turns on and off the pump. It looks like the photo below. Yours may be different model, but will be similar.

Controller is usually located close to water pump, often high up in that compartment. Be sure to get down and look up for it.

All switch wires will connect to the "SW" terminal on the controller. First thing to check is good connection of that wire. It is a spade terminal and may be loose, corroded or even fell off.

If connection seems good, get a jumper wire from a known good chassis ground and touch the "SW" terminal. Controller should cycle from on to off. Touch again and it should cycle from off to on. If not, you need a new controller.

Here is a drawing showing the way most of the coaches are wired.

Code2e, I finally found and gained access to controller. I checked connection on SW, still nothing. I checked to make sure I had ground and 12v at controller, good! I then jumped from ground on controller to SW and still nothing. I'm guessing that means I need to replace controller. confirm?

The switches are normally open momentary. If one of the switches is stuck in the closed position, the controller will not change it's signal going to the pump.
Remove the connection to one of the switches and go to one of the other switches and see if the pump will turn off. Do this to all three switches and I'll bet the price of your next cup of coffee, you'll find a bad switch. Those normally open momentary switches used by Fleetwood have a failure problem.
Here is a little easier schematic to read.

And I would start with the switch you used to turn it in when it wouldn’t turn off. If that’s not it, the wet bay would be the next to check.

The suggestions to check the switches are valid possibilities. Before going to that, it would be easy to verify if the controller was good or bad first. Just disconnect the terminal on the "SW" connection and use your ground jumper to momentarily touch the "SW" connector. This takes the switches out of the circuit and tells you if the controller itself works. Every time ground contacts "SW" it should change the mode of the water pump from on to off, or off to on.

If controller works, then try switches with the terminal reconnected to controller. If controller is good and you have a shorted switch, just connecting and disconnecting the terminal would change mode as well.

OK, where shall we meet up?
Do you do Quartzsite in the winter?

Haven't done Quartzite yet, haven't got wife talked into that but working on it. Ususally stay around Texas. Slip out of state for a month or so a couple times a year.
Thanks Again
