We have an 01 Fleetwood Southwind 36T. The onboard water pump can be turned on/off at 3 switches. Kitchen, bathroom & utility bay outside. The pump suddenly stopped working. It will not turn on from any switch. The 7.5 amp fuse in the 12 V fuse panel tests good. Schematics show a W/P Controller, but I don't know where to look or what to look for. Could it be an inline fuse somewhere or the pump motor simply quit?
Please point me in the right direction to trace this problem.

The controller is black about 3/4 inch thick about three inches square.
They hide them. Could be around pump, behind drawers near converter or DC distribution panel.

I would cycle all the switches again. If one switch gets hung up, the pump will not turn on.

7.5 amps indicates an OEM, wimpy pump most of the upgraded pumps require at least 10 amps, some 15.
Someone may have changed the pump, but not the controller or the fuses.
You have a latching controller, normally near the pump itself, on a bulkhead. Said controller comes in 7.5, 10, and 15 amp versions.
Made by Intelletec.
The pump should have an in line fuse, also near the pump.
Run dc straight to the pump and see if it runs... if it does you have a bad controller, or the inline fuse you haven't found yet.

If you didn't blow a fuse, the pump-moter may have burned out. If it is original, it would be seven years old. It may have been left running with no water a number of times in the past. Check for 12v power at the pump.

A quick way to determine if the pump is operational is to "hard wire" it. Run a new 12-V DC positive and negative wire with an alligator clip to the pump directly. If it runs, disconnect one of the wires. If it stops, then you know that wire is the problem. If not, then trace back thru the other wire. This is a simply way of "bench testing" without removing the pump.
Some models have an internal thermal switch and inline fuse. Here is the troubleshooting section of the Shurflo pdf:
TROUBLESHOOTING
PUMP WILL NOT START:
Check:
Fuse or breaker
For correct voltage (±10%) and electrical connections
Pressure switch operation and correct voltage at switch or
motor wires (as equipped).
Rectifier or motor for open or grounded circuit
For locked drive assembly
Also, most DC components must have 10.5V DC coming from the converter/battery.

My pump quit last week, after much searching I found an inline fuse about one foot before the pump. Yep, the fuse had blown. Sounds like that may be your problem.

I would have checked for juice at the pump like tundra indicated as the first step, I know tundra isn't but this lazy old man would start out the easy way.

If you have power at the pump and it does not run it could be the internal switch. There is a micro switch in the pump, (pressure switch), mine went bad but I had a spare pump for the day that would happen. I then went to a boat store and ordered a new pump front end which included the switch, about $30, put that on the old pump so I now have a spare again. The switch is about $2 but it is proprietary so not available.

The quickest way to determin the trouble is to do a voltage check at the head of the pump.
If you have 12-volts on one side of the pressure switch then you have power to the pump.
If you turn on a water faucet and have voltage on the other side of the pressure switch but the pump isn't running, bad pump motor.
No voltage on other side of pressure switch? Bad pressure switch.
No voltage on either side of pressure switch? Fuse, bad relay or broken wire.
