Encoder Sensors
not working
properly
Inspect assembly for
physical obstruction
Disconnected, loose
or broken wires.
Test Sensor.
Faulty sensor.
There are 2 identical sensor boards in the arrow housing.
2 sets of optos watch the notches on the edge of the wheel.
These sensors keep track of how many notches pass by to
determine wheel position. The home sensor will reset this count.
Check connections from opto sensors to I/O board.
Refer to wiring diagram. (Cable # CE26019, CE26011)
The cable with the white wire must attach to the front sensor.
Enter Diagnostic Menu, Wheelboard Section to see if game
recognizes sensor. Will flash “Notch Sensor” when sensor sees a
notch. Screen will also show the ticket value on the screen as the
wheel is turned downward.
Replace arrow sensor if needed. Part # AAPO26000
TROUBLESHOOTING GUIDE
Solenoid does
not activate
Inspect assembly for
physical obstruction
Disconnected, loose
or broken wires.
Test solenoid.
Faulty solenoid.
Wheel Board
communication:
Red and yellow
power LED’s should
be on.
Refer to “How to Remove Wheel” to access the solenoid assembly
Ensure assembly is loose and moves freely.
Check connections from solenoid to Wheel Board. Refer to wiring
diagram. (Cable # CE26000)
Enter Diagnostic Menu and select “Engage Wheel”. The solenoid
should now receive 12 Volts DC.
Replace solenoid assembly if needed. AASO26001
If it is off, then check 12 & 5 Volts DC coming into board on cable
CE26015 from Power Distribution Board.
If solid on, then it is not communicating with the motherboard.
Check A5CBL5900 USB cable. Swap cable with the light board.
Replace Wheel Board if needed. Part # AACB26000
Solenoid is on
all the time
Inspect assembly for
physical obstruction
Check for 12 Volts
DC on solenoid
cable CE26000
Refer to “How to Remove Wheel” to access the solenoid
assembly Ensure assembly is loose and moves freely.
If 12 Volts DC is always present, the Wheel Board AACB26000 is
faulty and will need to be replaced.
If no 12 Volts DC and solenoid is still engaged, the solenoid
assembly AASO26001 is faulty and will need to be replaced.

Solenoid is not
engaging.
The solenoid assembly should pivot as handle is pushed down.
The wheel will only turn if the solenoid is engaged. Refer to “Pivot
Assembly Exploded View” to identify worn parts to replace.
Refer to “Solenoid does not activate”
Wheel values are
a bit off target
Ensure the wheel is not
rocking backward as it
comes to a stop.
Arrow sensor needs
adjustment
The wheel brake should be tighten to ensure the wheel does
not rock backward over a notch when it comes to a stop. Enter
Diagnostic Menu, Wheel Debug, Select Engage Wheel and
spin the wheel fast. Refer to “How to Adjust Brake Tension”
Refer to “How to Adjust Arrow Sensor”
