Ed, actually, I do agree with you. I was sidetracked by some other project in my mind. If you look up at earlier posts, swapping outside leads is what I was thinking. Somehow, I got onto reversing the motor rotation, not simply the pot sweep direction.
Still, without a full circuit drawing, I can't be sure. I don't see anything that would prevent what we are suggestion from working. Sorry for the mix up. My fault.
