I am replacing and reqiring by 3 bilge pumps on my 10.8M. I have high water float switches in each of the original bilge locations and of course non of them work. I checked two of the switches and they are showing that they are good at the switch. The manual says that the bilge alarm is connected to the horn, but where is the relay or timer? The horn works (which is very loud), so I can only assume the problem is at the relay. I just need to find it, as I don't have a wiring diagram of this vessel.

for what it's worth, the relay on my '83 10 meter is in the hollow fiberglass sandwiched ceiling ductwork close to the horn location.

I added a manual override switch to the high water alarm in the event a bilge switch chooses to "stick" in the ON position.

This is interesting. I will have to check our 11 meter to see how it works. I never thought of it as having a relay. It probably uses the horn relay. I am not sure but will check it out.
