Water Pump ??
I've had the water pump quit twice now. First time I went out to investigate and found an inline fuse. Took it out and it was fine. Replaced it and pump fired up. Today, it stopped working, wait...

Brian.....Take a look at the ground wire and make sure the connections are good. Sometimes that wiring (ground) will disappear into the coach and you'll spend hours chasing it down. In this situation, just add a new ground close to the unit.
If you have several momentary switches throughout your coach, that means you have a water pump controller. They're about 2" x 3" and about a 1/2" thick, and are generally mounted within a foot or so of the water pump, usually up on a side wall of the water bay. You may want to check the connections on it. When a water pump controller is used in a motor home, it's wired differently than how common 12 volt wiring is done.
The hot side (+) of the water pump is wired directly to water pump and the ground is wired to the pump controller. Every time you push one of those momentary water pump switches, it connects to ground, either turning the pump on or off.
