On my 2015 409, my bilge pump float switch seems to have been stuck i.e. dry heaving for an hour or so then shuts off. I have had the boat for a year now and has done this three times now. The black switch box is screwed into the water collection cavity with two wires running from it.
The question, where can I get a new one and two I can take it out but can I just cut into the existing wiring and solder them in place and heat shrink to seal them up once I find the switch?
Thanks for all and any thoughts on this matter...Kevin
A new Rule Float Switch should be available from most good chandlers. If you need to join the wires you can make these connections watertight by using shrink wrap. Use the shrink wrap that has glue built into it. I replaced mine about 12 months ago. It’s a pretty easy job. I think I crimped on joiners and then shrink wrapped them.
Better would be to use in-line crimp connectors with heat-set glue already in them. Then you wouldn't need separate shrink wrap. Avoid soldering, which creates a hard joint that is susceptible to breakage due to vibration.
Rule is one brand. There are others. Nothing too special about float switches. If they fit they should work. And heed the advice above about doing the wire connections. Get a good ratcheting crimper and marine grade fittings. Solder is not usually a good choice for boat use.
The rule 1100A pump that came with some later boats has an integral non mechanical water sensor. I have had problems with these also. Rumor is that they drove slime and think it is water. There is a new 1100B that replaces the A but I haven’t tried it.
