I'm thinking that if to disconnect the pump from the control box and give it 9.0V, will it run? Think, gonna try this weekend, if my electrical engineer at work checks everything out and gives me an ok. Now, the question, where to find a 9V power supply with high enough current to drive the damn thing. By my primitive calcs, it draws about 20A.

Thoughts? Comments?
Sounds good. You will completely isolate the pump before giving it juice right? Maybe this unit will work: http://www.circuitspecialists.com/be...-csi3010x.html
