New Rule 1100 pump in, 10 amp fuse replaced. Everything good as new. I am looking to get some stainless or aluminum screen to line the mid-bilge area to keep some of the debris away from the pump.
Joe. I found my original "auto-every-two-second" Rule pumps. Will you describe the "lobotomy" operation to deactivate the auto-on-every-two-second part of the brain? Can't the wire that activates the brain just be cut and sealed off or is there more to it? (Which wire to cut - brown or brown with white?)
Thanks again to all for your input and for sharing your experiences.
John

The on-line site for Rule Bilge Pumps states that the Rule 1100 pulls about 3.8 amps and should be fused at 6 amps. The problem with a larger fuse develops when the the pumps jams. When a bilge pump starts up, there is an initial higher current flow. Until the pump gets up to speed and develops a voltage back pressure, the pumps pulls more than the 3.8 amps at running speed. If it jams and you have a higher amp fuse than the recommended 6 amps, the fuse won't blow; the pump will overheat and melt or possibly catch on fire.
See the Hull and Fittings Forum, Where did the water come from? Another case of a pump getting clogged and melting down.

John-
It's been awhile, but as I remember, the pump just has two wires, both of which have to be left attached for the pump to run.
The trick is to cut just deep enough in a circle about 1-1/2" down from the top of the pump to cut through the white plastic cover.
Lift the cover off, and note the printed circuit "Brain" of the unit.
Cut it out, and connect the ingoing and outgoing wires to it together. Solder them or use a good solderless connector and cover the metal with insulation, like liquid electrical tape.Test it out, it should run wheen the power is connected to the two feeder wires, and shut off when you disconnect.
Now go back and put the cover back on the unit and seal it up. I believe I used a good deal of silicone rubber to make a joint, then wrapped it with fiberglass packing tape once it dried/set up hard. The extra tape is for structural strength.
Don't put the tape on too soon as you want the acetic acid vapors to escape, rather than be trapped inside the pump where they will corrode the motor.
JB Weld may well be a better and stronger sealer, and may not need the fiberglass packing tape for structural reinforcement.
Good Luck with your "lobotomy" !
Joe.

The aft bilge pump on Journey On also seized. I discovered this when the circuit breaker kept blowing. When I took the pump off the mount, the impeller was stuck, which bolws the breaker/fuse for sure.
I don't know what the C-22 has for circuit protection, but the C-25 has circuit breakers on the DC switch panel for the aft pump. And I have no intention of wiring around that.
The original pump is/was a Rule 1100, just as mentioned above. It had an integral float so that the pump only came on when there was water present. I ordered a new Rule-Mate 1100 A and the darn thing now (according to the brochure) senses the presence of water by capacitance. The claim is that it will not pump oil and no mention of cyclic operation is made.
My question is, if you got this far, does anyone have experience with this pump?
