Replaced the float swithch and will see the next time out if that sloved the problem. I suspect that it will and was an easy fix. I do have a question on the auto function on the bilge pump. What is the funtion of the auto on position for the bilge pump. Its my understanding the power to the float is always hot to activate the bilge even when the main power is off. If thats the case am I correct that the pump is always in auto mode and I do not have to put the switch in auto mode. Thanks again. Rick T
