We're thinking along the same lines here regarding the pump motor and 
trying to save John a lot of work in case it's not the main board ;>)

The motors in the 7000 and 9000 are the same spec-wise, but carry 
diffent part numbers. They are both steppers (4 phase 200 cycle HB 
types) with the same control voltages.
