7.14.5 Secondly, with the actuator motor still disconnected, connect your

multimeter between the orange wire of the wiring harness and ground.

Turn the ignition switch ON. Move the left joystick to the full-forward,

center, and full-reverse positions. The multimeter should read battery

voltage in one of the positions, but read 0 (zero) Volts in the center and

opposite position. Perform the same test on the black wire; the

readings should be reversed.

• If your readings did not respond accordingly, the control board

has failed; replace it.

• If your readings were OK, continue.

7.14.6 With the ignition switch OFF and the actuator motor still disconnected,

disconnect the wiring from the right actuator motor (M1), the right load

pin (L1), and the left load pin (L3).

7.14.7 Connect the wiring for the right actuator motor to the left actuator

motor, and the wiring for the right load pin to the left load pin.

7.14.8 Turn the ignition switch ON. Move the right joystick forward and

backward while watching the left actuator for movement. The left

actuator should move with the movements from the right joystick.

• If the left actuator does not move, the left actuator has failed;

replace it.

• If the left actuator moves, check the function of the left joystick.

7.14.9 After replacing any failed component, make sure to reposition the

wiring harness in the correct configuration and secure it with wire ties.

Turn the ignition switch ON and test the function of all three circuits:

right, left, and side.
