Throttle Service
The throttle controls airspeed and lets you change the view to find enemy aircraft. See Figure 31
on page 54 for an exploded view of the throttle. Perform the following steps to replace the
throttle:
1.
Remove the four (4) Torx screws that secure the Throttle assembly in place and lift the assembly
straight up.
2.
Disconnect the two wire harnesses and the ground wire that is clipped to the frame.
3.
Reverse these steps to install the new Throttle. Be sure to reconnect the ground wire. Install
with the button toward the inside of the cabinet.
Replacing the Throttle Pot or Gear Wheel
The Throttle uses one pot (potentiometer) to relay its position to the software. Refer to Figure 17
and perform the steps below to replace the pot or the gear wheel. See page 54 for an exploded
view drawing.
To test the pot
, either observe the numbers next to
Throttle
in the
Calibrate Stick Test
screen,
or power off the game and test resistance at the pot. While moving the throttle, you should see a
steady linear increase or decrease in resistance or numbers, with no jumps.
1.
Remove the throttle from the cabinet as described above.
