Hi Walter. The alarm is tied into the float switch for the high water pump, which is on the aft bulkhead of the ER. But that may or may not be your problem. If you read through this thread you will see that the HW alarm set up on the 400 is quite complex with multiple relays tied into it.
Lots of good info in this thread. I ended up disconnecting the function that activates all of the pumps in the boat when the HW alarm comes on. I personally donít think that functionality provides any value and causes big problems. But others may disagree.
