Treasure quest uses an electromagnetic clutch to engage the center wheel. When told to spin we apply 24 volts DC from the J4 connector on the main board to the clutch to pull the metal plate on the back of the center wheel towards the clutch. Over time the metal plate on the back of the wheel will build residual magnetism and be attracted to the clutch when it is not engaged. To combat this we use thin shims between the clutch and the plate to space the wheel from the clutch allowing it to not be manipulated when the clutch is disengaged. If a customer can grab the wheel and manipulate the inner wheel then the then the shims have started to wear down allowing the plate to be moved with when the clutch in not engaged. Each cabinet is unique and will require a different amount of shims to space the wheel and the plate we recommend using anywhere between 3 to 5 shims on the game. The part number for the replacement shim is VW1153.
When the shims do wear down moving the inner wheel to manipulate the center wheel causes a lot of vibration in the game, to deter customers we incorporated a slam tilt on the back of the game and a tilt bob above the main board. These anti cheat features need to be properly adjusted to correctly function see below for the location of these devices.
