Default Re: Water pump and hot water heater ignitor issues

Did your water pump work after switching the hot wire from the appliance?

If not, you might want to check the ground/negative wire that go to a grounding block that is located by removing the refrigeraor access/vent cover on the side of the coach. It is usually mounted at the opening of the side cover. There are many white wires going to this block and sometimes if terminal screw(s) are not tightened a wire will come out/loose and the units that it goes to will stop working because the circuit is not complete.
I had this happen in our coach, the ground wire for the 12v for kitchen slide came out of the terminal block, our lights, range ignitor and range hood fan/lights all stopped working at the same time.
It took me about four hours to find out what had happened. I reinstalled the ground wire and tightened all the terminal screws, all is well.

I believe ALL the ground wires for the 12v house batteries go to this grounding block.
