Earl: I just had to make sure that the power and ground were there for the pump to run off of. The earlier posts didn't specifically state this, just the fact that the pump will run with power and ground applied to the 2 pins. you could try messing with the microswitches, but again let me point out that you would have to have a triple failure of the microswitches for this condition to exist. Let me look at a better diagnostic manual at work today and I'll get back to you......Gilly
