MAIN HUB TROUBLESHOOTING GUIDE
Step # 2
Troubleshooting topics specific to a unit.
Spindle Unit Only:
If the Prize Chute Sensors are blocked, dirty, or faulty - the Prize Hub will not allow any spindle prizes to be selected and
will show the entire row of prizes as "Unavailable".
Solution:
1.) Remove 4 of #2 square head screws from L Brackets in rear of prize chute wood box. Wood Box will now slide out
front of game. Remove Prize Chute Sensor by removing the 4 Phillips bolts that secure sensor to black plastic mask.
(The black plastic masks must remain attached to wood to provide alignment for the sensors.)
Clean emitters and detectors. Ensure they are pointing straight out and no components on boards are bent.
2.) Inspect cables between sensors and to 1803 board. (AACE1818, AACE1823) Replace if needed.
3.) Ensure AACE1823 cable is plugged into correct socket on 1803 board. (Gold socket) See diagram.

4.) Replace both Prize Chute Sensors. (AACB4402)
5.) Replace 1803 Control Board. (AACB1803)
Capsule Unit Only:
If pivot motor test fails on power on - the Prize Hub will not allow any capsule prizes to be selected and will show the
entire row of prizes as "Unavailable".
Power game down, wait 10 seconds, then power game ON.
Immediately at power on - The pivot motor will move and test home sensor.
If Motor does not move:
Check for 12 Volt DC at motor.
Check for disconnected, loose or broken wires on motor and cable to 1803 board.
Replace if needed. (AACE1812, AAMO1800)
Replace motor. (AAMO1800)
If Motor does move, but capsule stepper motor will not start (it will also be very hard to turn by hand):
Ensure black plastic cam is spinning with motor as it turns.
Check for 12 Volt DC between yellow and blue wires at sensor. 5 Volts between blue and white should drop to zero
when blocked.
Check for disconnected, loose or broken wires from sensor to 1803 board.
Replace if needed. (AACE1812, AACB4401)
Replace sensor. (AACB4401)
