Ball-gate sensors Operaon
There are two magnec sensors located under the primary ball gate assembly. The primary ball gate assembly has a magnec
aached underneath so that when the assembly rotates it will pass over one of the two sensors. When the ball gate assembly
moves counter clock-wise, it will pass over the sensor for the closed posion and stop the assembly. When the ball gate assembly
rotates clock-wise, it will pass over the sensor for the open posion and stop the assembly. Using a volt meter, when the magnet
passes over either of the sensors, that sensor will have no voltage present. When the magnet is not over the sensor it should read
+5 volt of DC power. With the power o on the game, the sensor is normally open.
** WARNING ** Never manually move the Primary Ball Gate assembly as damage will occur to the motor gearbox assembly below.
Ball-gate sensors Access
Remove the two screws that hold the gate cam to the Primary Ball gate assembly. Slide the Primary Ball gate assembly out.

Ball-gate sensors Removal
To remove a sensor, disconnect the two pin connector. Then unscrew the e-wrap and push the sensor out. To install a replace-
ment sensor, insert the connector from the top through the hole and push rmly down. Aach the wire harness and re-install the
wire e.
