Hold the traction reversing actuator and springs in
place in the top cover and install the traction reversing
actuator into the recess in the bottom half of the han-
dle. Lower the cover onto the handle base.

ping screws into the top cover. The screws must be instal-
led into the existing threads. Ensure the screws are started

to retain the top cover.
Control Module
CHECK
The control module converts analog signals from the con-
trol handle to digital signals for the controller to read. If the
controller is reporting an input error fault code, then the
control module may be malfunctioning. Check the control
module using the following steps.
1.
Remove drive unit compartment covers for access to
the electrical components, and raise the drive tire off
the floor to prevent unexpected movement. See the
section
Periodic Maintenance
8000SRM1644.
2.
Connect the battery and turn the key switch to the
ON
position. Make sure the parking brake switch is in the
OFF
position.
3.
Connect the negative voltmeter lead to the negative
battery cable connection at the controller.
4.
Disconnect 6way connector B, check pin 3 (on the har-
ness side) for +24V. See Figure 19.
