Mainship 400 High Water Alarm

Anyone had experience with the high water alarm system on a MS 400?

Crossing back from the Bahamas today, 25 miles offshore, our high water alarm went off, and the indicator lights for all three bilge pumps came on. After I popped three heart attack pills, I checked all the bilges and all the pumps. No water coming in anywhere. Aft pump in laz is running, but there is no water in laz. Mid pump in engine room is running, but no water. Fwd pump light is lit, but not running. High water pump is not running.

Disconnected the alarm and came back to the home slip. It seems to me to be a failure in the High Water alarm, but I can't find a float switch or anything to trigger the alarm.

Maybe the High Water Alarm is tied into the float switch for the high water pump? The float switch for the pump SEEMS to be working. When I turn the knob on the side it turns the pump on.

Anybody got any advice before I start tearing things apart?
