NOTE 3: The motors in the machine are arranged in a 7 X 10 matrix. This means that all motors have a wire
common to all other motors in that row. Example: All motors in horizontal row “A” have a violet wire in common
in the main motor harness from the control board. Likewise, all the motors in a vertical column have a wire
in common. Example: All motors in column 2 have a white wire in common in the main motor harness from
the control board.
The following is the wire color guide for the motor matrix in the main motor harness:
