RV Repair: Truck Camper electrical, truck camper, volt battery

Question
My water pump is not working when hooked up to the camper electrical system. I took it out and and tested it on a twelve volt battery and it worked. Everything else works, lights, fridge, AC, smoke detectors, etc.

Answer
Bill, It sounds to me like you lost power to the water pump and the best way to test is to start at the switch and see if there is power there. If not you may be able to find power close and get it there. If it is there make sure it is getting out the other side of the switch. You should be able to locate it from there. Thanks, Bill P.S. If there is power there then make sure that your ground is good.
