A couple things come to mind. I wonder if it would be worth doing a factory
reset just to clear up any odd things. You would lose scores or adjustments
you've made.

Next up, the harness that moves with it, and then switches or optos that let
the game know where the ringmaster is. Some things are powered different in
test so that could account for working in test but failing in game play. You
may have to go over it more thoroughtly to sort it out. LTG

Don, and Lloyd; Mike here. Thanks for the replys. Everything is
connected, and works 100% in test mode. All of the switches are
adjusted exactly like the manual says, and are recognized perfectly in
test mode. In test mode you use the up, down buttons to run the
ringmaster forward, and reverse, and it works perfectly. The only
problem is that there is no reverse motion when game is turned on, or
in game play mode. I believe that I was told that the control voltage
will drop to zero for a split second, and that signals the board to run
the motor reverse direction. I was just hoping that someone had seen
this before. Mike.

I’ll bet the directional drive, solenoid 39 is not working. During
ringmaster test when you push the + and – buttons changing the
direction of the motor, it may appear as though the motor is reversing
direction, but my guess is the motor is in fact only turning one way.
So get your multimeter out, put it on the yellow/white wire on the
motor drive board that is J1-2, then get into your solenoid test menu,
select solenoid # 39, verify you have 12vdc at this point that
momentarily drops low as you do the solenoid test. This is your
direction drive, when low motor is going to run one direction, high it
runs the other direction, but during this test the motor will not be
running, but voltage should switch. If this voltage is not switching or
not there at all trace back to driver board J110-4, if not working
there possibly the driver IC on the driver board U3 ULN2803 could be
bad
