Thanks Gilly,
Thats a big help. I am currently working on the pump and have it on the bench. I removed the pump wires from the circuit board and put 12 volts directly to the pump and it works like a champ.

Now I'll check out the wires you mentioned and recheck the fuses.

Where are the microswitches located? On the circuit board inside the pump housing?
