Problem
Probable Cause
Remedy
a. Game says you won tickets even
though wheel is still spinning.
b. Game gives tickets as soon as money
is inserted during attract mode.
c. Game ends after slow spin, and gives
no tickets.
a. Weak encoder sensor. Replace sensor.
(AACB1901)
b. Attract mode spinning wheel should slow
down enough so it will not trigger win.
Tighten brake assy. (see Brake Adjustment)
c. Motor assist should spin wheel for slow
spins. Check menu screen – ensure it is not
set to “Abandon Game”. (see Motor Assist)

Issues
Open left front door and push menu button to enter menu
Check if value on monitor matches wheel position.
If it does match:
1.) Look for “motor watchdog error” on screen. Refer to
Motor Watchdog Error section
2.) Encoder sensor not reading properly.
Go to Wheel Encoder Sensor section below to adjust sensor.
Replace encoder sensor if needed. (AACB1901)
If does not match:
Manually spin wheel 1 complete revolution to ensure
home sensor is being read.
Important: Always spin downward
Encoder sensor signal not reaching I/O board.
1.) Check cable AACE1616 from encoder sensor to I/O board.
2.) Go to Wheel Encoder Sensor section below to adjust sensor.
Replace encoder sensor. (AACB1901)
3.) Replace I/O board. (AACB1900)
Encoder sensor always “sees” home
position.
If either green LED on board is always ON
as you spin wheel - Replace encoder
sensor. (AACB1901)
Game pays 10 or 75
tickets every game.
Encoder sensor signal not reaching I/O board.
1.) Check cable AACE1616 from encoder sensor to I/O board.
2.) Replace encoder sensor. (AACB1901)
3.) Replace I/O board. (AACB1900)
