Well I got my sewing machine back from 20 plus years!! wiping it down now!!! But it is sewing backwards!!! the polarity is reversed on the motor! Now what? don't know if I can fix it or not, may need to get a new motor I think...

It is a Domestic model W...will post pictures shortly

what do you mean sewing backward? Does the fabric feed backwards, or do you mean the handwheel turns away from you. Some machines did turn "the wrong way". I don't believe it's possible for the polarity to change unless someone physically did something to the wiring of the motor.
