I have a brand new (reman) wiper motor from a 69 GTO. The wiper actuator was broken, but I want to test the motor. I have removed all the casing minus the motor (stator, commutator, etc). The motor is a brush motor with a Poss and Neg lead that I try testing using a 9V battery. However, I know nothing about testing these motors. When I hook up the 9V battery, the magnets in the stator activate, and the commutator assembly does not spin...but is magnetized to the stator (or vs versa). Even if I turn the Commutator to get the polarity opposite, it does not begin to spin. Does this mean that the windings/wiring in either the rotor assembly or the stator are backwards?
