Is it possable that one of these will work?

These look like mine except that they have an external ground. HWH web site says theirs are grounded internally. I am not sure how that works exactly. I can see that the positive from the battery goes to the positive lug on the motor through the solenoid and then connect to the pos brushes inside the motor. Somehow the negative brushes must connect to the motor case through the pump mounted to the frame. I suppose the only way to see if there is continuity to ground is to take the end plate off and ohm it out from the brush to the case. Anyone know an easier way to check it?
