12 volt water pump problem

Dry camped last weekend in our 3953 Canyon Star and water pump worked great, turning it on/off from either bathroom or kitchen area. Went to full hookup campground this weekend and when we went to leave the pump would not turn on. Checked fuses and nothing blown. Any ideas? Thanks!

Turn on the pump switch and with your volt/ohm meter check the voltage at the pump. If 0 volts then you have a blown fuse. If you have in the neighborhood of 12 volts, and the pump is still not working, the pump motor has probably seized and the thermal protection is bad. Pump needs to be replaced. Not a difficult job.

There is very likely a pump controller (relay) between the switch and the pump. Guaranteed to be if you have more than one pump switch. Sometimes there is also an inline fuse near the pump itself. Either of those could be out.

Check and clean the ground wire on both ends especially at the frame. Sometimes just disconnecting and reconnecting wires will make contact.

Having 12v present doesn't mean pump is shot. Typically a controller is in the circuit. Switches connect to controller, controller supplies ground to the pump motor. 12v is always present, only the ground is switched.

Short the black ground lead from the motor to ground, if pump starts controller is bad. I made up a jumper to run the pump in case of controller failure. Connect ground going to controller and negative lead to pump together.

70ChevelleSS is exactly right - the pump controller switches the ground rather than the hot side, so the +12v wire to the ump is always hot. Even with the pump switch off. Try it to verify.
