Motorhome water pump issue

Last time I used mh I drained the fresh waste tank. Went out to test for next trip coming up and pump didn't run. Found a fuse in back exterior passenger fuse panel it checked okay. Where might the water pump be and how else can I test it?

    Updated found the unit that control the water pump out was behind the sewer dump. It had fallen and shorted out.

    Monoplex pump controller......LINK

    Could be by 12V DC distribution panel, around converter, in compartment with water pump, inside a small outside compartment, behind drawers....it's kinda like a scavenger hunt, you just have to look in every conceivable place and then look some more.

    It does have multiple switches, and it's a 2002 National Tradewind. Sounds like I need to find the pump. What dies the controlling unit look like?

    IF you have more than one ON/OFF switch for operating pump then the 'pump controller' may be the problem

    Be a little more specific, Make, model, yr. Some are under the sink, some in the fresh fill compartment.
