Does your rig have multiple switches to turn water pump on? If the answer is yes, look around near the 12 volt DC panel for a water pump controller. Mine is hidden next to drawers in that area.
The water pump controller, or some, switches the ground. testing the pump circuit would require disconnection both wires.
Water Pump controller
Only one water pump switch, on the monitor panel. Disconnected wiring completely from water pump. Fused wire going to pump, fuse was good. No help. Still short to ground on load side of monitor fuse with pump disconnected.
