rule bilge pump
My Rule 750 bilge pump (has internal float switch) has three wires -
labeled - Neg, Pos. and Main Pos. Can anyone explain the two pos wires? I cannot find my owner manual. paul |

Neg - negataive (Duh) Pos - a switched supply to run the pump from a manual control Main Pos - to a full time supply (this feed the float switch so the pump is automatic. When I put these in, I usually use a SPDT-CO (center off) switch so the owner can select auto (where you leave it), manual that will usually let you pump the bilge down more than the built in switch likes to do and off is to stop pumping when there is something in the bilge you don't want to pump overboard until you are ready.

Matt Make sure you use good crimped connections and cover each with heat shrink tube. Make sure to leave it so that you can replace it when the poor quality float switch stops working. External float switch complaint: I noticed that they now make the external float switch easily removed from the pump. Can't make the switch better, but they seem to be admitting that it needs to be changed once in a while and they should make it easy to do. |
