@laming, these open frame AC PulMor motors do have what appear to be two leads on the brush plate, but contrary to what one may think, these are not identical to the connectors of a DC motor. In these, the field and armature are in series, and the order of such determines the direction of rotation, and that is what the e-unit switches around with the various drum positions.

This is seen here:

And described in the service documents here:

To bench test the motor sans the e-unit, you will need to jumper a field winding to one of the brushes, supply ground to the frame, and hot to the other brush.
