    Re: Determining correct wires from stepper motor

    Hi,
    there will be a low resistance, several Ohms or less between A+ and A-, and also between B+ and B-, but open circuit between any A and any B.

    As for the difference between + or -...who cares. Just wire it up and then swap just one winding if the stepper is going in the wrong direction.
