I've found the pump.
I've filled the tanks.
I've hit the switch. Nothing.
Found three relays by tracing the wire, push them with screwdriver, and all three (what?) make the pump run. But it doesn't pump any water.
So what am I missing? Unfortunately I don't have many hours on the boat yet, as I just re-positioned it, but will be there for the day tomorrow.
Looking for some ideas to try and see what the deal is.
I'm going to try and trace the relays somewhere, but that looks very difficult due to the next stops on the wiring (through raceways).
I'm thinking to get water flowing, the pump would need to be primed (I thought most freshwater pumps were self priming?)
What seems weird overall is why are relays needed? Wouldn't this just be a single on/off switch and a pressure switch at the pump?
Thoughts?
