Section 6. Component Procedures Wiring Harness
Wiring Harness NOTE: For replacement parts information refer to Parts Catalog. The wiring harness is designed to connect the electrical components of the pallet truck.
•
Replace terminations with exposed wire visible at the connectors. Damaged terminations, exposed wires, or damaged connectors can cause operational failure of the truck
During troubleshooting and repairs, it is sometimes necessary to unmate a connector, move a harness, cut a cable tie, or remove the wire from a bracket. Note carefully the location of the wire and all protective or securing attachments before moving the harness. After repair, return or replace all protective and/or securing hardware to its original condition. Protective materials are necessary to provide reliable performance of the interconnect system.
Figure 6-6. Wiring Harness
All wires in the harness are marked with a wire identification number. These numbers correspond to wire identification given in the schematic. All connectors are represented by “J” followed by a number. See “Schematics” on page A-9.
In addition to the wire identification number printed every 1 to 1.5 in. (25.4 to 38.1 mm) on the wire, there is a wire marker at each termination. If the marker is missing or unreadable, remark the wire to permit easier identification. NOTE: It is normal to find unused connectors for uninstalled options that have had heat shrink applied over them and have been strapped to the harness.
Inspection Whenever working on the truck, use care around wiring harnesses. •
Do not pull on wires
•
Carefully mate and unmate all connectors
