Bilge wiring

[Before the Bell]

Can anyone inform me about a Hunter 25 1976 bilge wiring. My 25 has a green, red and black wire for the bilge. My bilge pump has a brown striped, black and a brown wire. I can get the bilge to work manually but not automatically. Any help appreciated, thanks.

Bilge

I just put a new Rule mate 1100 in, the wiring instructions are confusing and mine required a seperate switch. for auto and manual.

Experiment.

Did the pump not come with wiring instructions? Maybe you could sneak a look at West Marine. Or do a Google search.The black is obviously the ground wire. One of the other wires goes to the panel switch for manual operation. The remaining wire goes directly to a battery, usually from the back of the battery switch. This wire is always hot so that anytime the float switch comes up the pump will come on.I am not familiar with the H25 wiring, maybe your bilge does not have the "hot" wire. It is easily installed.

what Ed said

I agree with Ed. When you say manually, do you mean with a breaker switch? Have you checked the automatic circuit for a blown fuse and have you checked the float switch for continuity when the float is raised?
