privcap1 Posted April 7, 2021 Share Posted April 7, 2021 Hello, Would anyone have a detailed wiring schematic for the water pump and switching system for a 2003 Monaco Windsor? One that includes all fuses. My water pump failed to come on yesterday. I have power to the hot wire at the latching relay but no power on the hot wire going to the pump. I bypassed the latching relay by removing the load and ground wires and connecting them with a 10 amp fuse but still no power on the hot wire going into the pump. The four fuses related to the water pump system are good. Thank you. Link to comment Share on other sites More sharing options...
Dr4Film Posted April 7, 2021 Share Posted April 7, 2021 Don't know if yours is wired like mine but my Water Pump Controller activates another relay that is heavier in gauge and uses larger wire that runs to the pump.

DavidL Posted April 7, 2021 Share Posted April 7, 2021 Is the pressure switch closed? Link to comment Share on other sites More sharing options...

It appears the coach's complete water pump schematic is hard to find. 17 minutes ago, DavidL said: Is the pressure switch closed? Thanks DavidL, I installed my backup pump and still nothing.

waterskier_1 Posted April 7, 2021 Share Posted April 7, 2021 I could not find a diagram in the 2003 Windsor wiring diagrams for the water pump circuit. I'm attaching one from 2003 Dynasty Wiring Diagrams. I think they should be quite similiar.2003 Monaco Dynasty Wiring Diagram Water Pump Circuit.pdf Link to comment Share on other sites More sharing options...
