You know something.  I must have swapped wires up on the tower.  I thought I
had the explanation figured out in my head because I was sure that 2 months
ago, I wired it correctly.  But now when you put it in the clockwise and
counterclockwise terms, what you say makes sense....

Yeah, that's another way to do it.  I didn't think about that.  But rather
photocopied the scale.  Use white-out to take out the numbers and letters,
copied that and then wrote in new numbers and letters.
