STEERING WHEEL SERVICE

If the Steering Wheel values cannot be set within the appropriate ranges in the Input Test menu, an adjustment of the potentiometer is needed. If the potentiometer cannot be adjusted appropriately, it needs to be replaced. The gears should be greased every three months.

CAUTION!
The Control Panel weighs approximately 10 lbs. Use care in moving and handling.
The Steering Wheel motor may be hot after use. Wait until it cools to service.

ACCESS
  1. Turn off the Indy 500 Twin game.
  2. Remove the six tamperproof screws that secure the Control Panel to the cabinet on the affected side (see Figure 61).
  3. Carefully pull the Control Panel away from the cabinet, using caution to avoid damaging the wiring.
  4. To replace, connect the wiring harness, lift into place, and secure the six screws.
