General
The removal and replacement procedures for the
following electrical components are covered in this
manual:
• Display Switch Cluster
• Power Distribution Module (PDM)
• Lights
• Sensors and switches
• Battery
Some of the components used are made of plastic.
When using screws to replace and install plastic
components, the screws should be rotated
counterclockwise until the screw thread turns over
the last thread in the plastic part. The screw can
then be turned clockwise to make a connection.
This prevents "cutting" new threads and damaging
the existing thread in the plastic part.
If any welding must be done, obtain proper
authorization from a Resident Service Engineer. If
authorization is given, be sure to follow the
procedures in the CAUTION below.
CAUTION
When welding, always disconnect the negative
battery cable from battery and disconnect the
ground wire from the ground stud on the frame.
See Figure 1. To prevent damage to the Electronic
Control Unit (ECU), remove it from the lift truck.
