New to me 2013 R25sc and I'm trying to find out how the factory bilge high water alarm is configured. Someone along the way has clearly mis-wired what I have. My forward bilge pump was not working in manual, only auto, and I've since figured out (after pulling fuses) that the auto was being powered by the high water alarm circuit. Removing the high water alarm fuse finally got it to stop cycling in auto, and also stop beeping the high water alarm when it was turned on and the pump was cycling.
There is a white, round clamp to port of the forward bilge pump that has nothing clamped there. Was that a float switch for the high water alarm? Anyone with a similar boat, is your high water alarm float cylindrical or one of the Rule type lever float switches, and where is your float for the high water alarm located?
Thanks, pictures are great if you have them.IMG_5179.JPG
 
I believe the power for auto and manual operation of both bilge pumps are on different circuits and battery banks on all the boats. This is done for s
redundancy so that the bilge can be manually pumped even if the auto circuit fuse is blown or battery is dead. The high water alarm is also on the auto circuit.

On our 2014 R27 both bilge pumps and the high water alarm use a Johnson Ultima electronic float switch. The High water alarm switch is mounted to the bulkhead near where the ell bracket in your photo is.

Thanks for the reply. I have fuses for each pump auto operation and the high water alarm in the port forward locker, and each pump has a breaker for manual operation at the dc panel. So it looks like I will need to use the power that is currently going to the forward pump from the high water alarm circuit and tie that in to a new johnson float switch, and hope that I still have wiring in place for the auto circuit and the manual circuit which is not currently hooked to the forward pump. Not a very accessible location and really hoping I don't have to run new wires from the panel.

Did you ever figure out how it was supposed to be wired and work? Also any pictures of where the high water alarm is installed?

Thank you

Yes, I ended up finding the wire for the high water alarm that had been disconnected. I put the forward bilge pump auto sensing wire back on the forward bilge pump where it belonged, and I bought an electronic float switch ( https://www.amazon.com/dp/B0BXMS25PB?ref=fed_asin_title ) for the high water alarm. I installed it right where the broken white plastic piece is in my above photo that is directly below (in photo, to port in reality) the bilge pump. You just want that high water sensor a little above the bilge pump sensor.
