No power to my pump? Any thoughts? Was just working and overnight quit.

Might be better answered in the Monaco area. But two places to look for a fuse are the 12volt panel in the bedroom or the run bay front drivers side.

Thanks. I checked those and no issues. Something hidden somewhere.

Your water pump may be controlled with a latching type device that recieves a signal from any of the switches. I have 4 switches that I can start the pump with.

It looks like this

Mine is located close to the water pump.

I also have an inline fuse that provides power to the pump.

Jim is right on. My latching controller went out this March and it was an easy and cheap fix. I found an upgraded model for about $40 shipped. I was told by Monaco that Oregon coaches had the controller in the basement and Indiana coaches had them over the door by the pump switch.

"Woody57".....If you have multiple water pump switches in your coach and they are momentary switches (push them and they snap back), you have a latching controller that looks like this.....

Again, if you have what I've described, your water pump is wired a little differently than you would expect. The hot side (+) of the water pump is wired to power all the time. The negative side (-) is connected to the controller. When you push a water pump switch, it momentarily connects to ground and connects the ground on the water pump.

To check for a controller failure, take a volt meter and check the hot lead (red wire) at the pump, it should show 12 volts. If it does, your controller is most likely bad. The quick fix, in an emergency, is just run a ground wire to the water pump. This will get you going until you replace the controller.

Intellitec makes the controller and is available on Amazon. I carry a spare.
