Help pls. 2003 Monaco Diplomat Water Pump Fuse Location

[jannlanz]

Hello, I am on the road with my 2003 Monavo Diplomat and can not locate the water pump fuse box. Water pump is new and worked a month ago just fine. Can someone please tell me where I can find its fuse? I've been on the phone with rv repair people and we still can't locate and it. Traveling with dogs and it would very very helpful to check that fuse. Nothing I have seen anywhere has been labeled "water pump". Thank you so much!!

Just to be sure, my water pump on my Monaco had TWO shut off switches. On inside the coach and one in the wet compartment right by the pump.

You might also see something like this as an inline fuse:

I'm remembering bits and pieces from my friend that had a voltage tester yesterday. He said there was no power at the pump.

I've been looking at pics and reading and I still can't figure out what they are taking about. The pics I've seen are of the water pump area, but I don't know what they look like. What color is it and what kind of fuse would it take? Thank you so much.

Most inline fuses are black or clear and operate as a twist type of connector. On your water pump it may be a 15 amp fuse but once you pull the old fuse out you can match it to make sure that you have the right size.
Monaco had a habit of not labeling or mis-labeling their 12 volt fuses. My Monaco coach has four separate 12 volt fuse panels. Sometimes it is a trial and error search for exactly what fuse powers what.

You should have multiple switches for your water pump. That means you have a small CONTROLLER for the pump itself. It is rare for the water pump fuse to blow. There is NO in line fuse on your water pump. There are 2 locations for the fuses on your Monaco. At that inside fuse panel and the odds are the water pump fuse is located in the outside LF storage in front of the LF tire on that LARGE fuse panel. THAT black cover panel will tell you what each fuse goes too. The odds are the pump controller is bad and is usually located in the outside water bay area on the wall behind the white panel. Doug

Mine is in the bath room next to the large grey 110V breaker box. It's 3x6" and has 20 fuses in it BUT non are labeled water pump. You could test each fuse in the hopes of finding one blown. When mine stopped working it was the crimp connections at the pump. I would call Monaco customer support at 877-466-6226 with the last six of your Vin #. If you can turn the pump on from various locations it could be the latch relay.

Also, there are 12 volt fuses located in the bedroom upper cabinet. Not one of them says water pump on them. Thank you.

Since the water pump was changed, it is possible that there is an inline fuse located right near the water pump itself.

Most of my 12v fuses are in a panel in the closet behind a panel. You have a few screws to remove and there they are. I am not sure about yours but I would look there.
