Hi, wonder if someone can help?  Thought water pump had packed up in opur 2004 Countryman so bought another but still didn't work.  Tested the original by wiring it to Leisure battery direct and it pumped water.  Power doesn't seem to be getting to the switch and I can't seem to see how to get at the wiring to find out what the trouble is.  Have tried a replacement switch so I don't think it's that.

Thanks for any help.

 hI tanners, i don,t know much about fc camper set up but ,i am electrician.Firstly pump and its wiring should be protected by a fuse (like in a car circuit) which would probably be located somewhere near the battery.If the pump has become faulty this would blow the fuse.If thats ok you could test using a cheap multimeter.on the 12v dc scale follow the wiring with the negative side of the pump connected to the black lead on the tester,test with the red lead starting at the fuse,then test both sides of the switch.Remember the pump will not work if the negative is not present,ie does the negative go back to the battery or is it looped of another 12v applience ie a light  etc it could have become dislodged .the way to check this would be to run a temperary flying lead from the negative straight to the battery,using the existing positive supply from the switch.Also have you done any work to the camper an accidently damaged the wiring?

Hope this helps GCB
