The Mini Playfield motor will only rotate one direction (clock-wise if that matters).
The optos are good, because i can move the board by hand and observe, in the Mini PF test, that the system sees the board toggle left and right.
I did replace the motor control board just about a year or two ago when the motors wouldn't move at all.
is this yet another motor control board issue?
It would seem that if the motor works in one direction, it's working, and I would assume that the direction is reversed by simply reversing polarity in the motor control board output, therefore suggesting it's a motor control board issue.
Thanks for reading!
