I replaced the water line between tank and sink in my camper.  Now the faucet (actually the pump) does not work.  I have checked the fuse and all connections.  Everything seems tight, and the fuse is good.  What did I do, or more importantly, what do I need to do to find out what is wrong?  I do not have a circuit diagram.  Everything worked before, except the water line was full of crud.  Now it is clean, but water won't flow.  I suppose it is just a matter of using a multimeter and finding any broken path.  Lots of wires and connectors it seems.
