7.12.5 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 right 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.

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

disconnect the wiring from the left actuator motor (M3),the left load pin

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

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

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

7.12.8 Turn the ignition switch ON. Move the left joystick forward and

backward while watching the right actuator for movement. The right

actuator should move with the movements from the left joystick.

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

replace it.

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

7.12.9 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.
