The main wheel sensor is located in
the back of the game attached to the
main wheel support In the 12 O'clock
location shown in the to picture to the
right.
The sensor will have three wires
coming from the sensor (RED, Black,
and Blue) the red is 12 volts positive,
the black wire is your common, and
the Blue wire is the singal wire. When
the wheel position break goes
throught the sensor the red LED will
light on the back of the sensor
indicating the sensor is "seeing" the
wheel break. Now is also the time to
check for 12 volts to the sensor and
that you get a voltage change accross
the blue wire when the sensor is
blocked.

Main Sensor Issue
With the game on, You should be able to
maunally move the score wheel by hand in
the back of the game to see if the sensor
break is attached to the wheel and if the
sensor is picking it up. In the picture to the
right you can se that the sensor is "seeing"
the sensor break even though the break is
far to the left. This means the sensor has
failed.
