maintenance as defined in the Maintenance Allocation Chart located in Appendix B. Before performing any procedures in
this section, use the Unit troubleshooting procedures to identify and locate the parts on the trailer-mounted, generator-set
powered, air conditioner requiring maintenance.
4-19. ELECTRICAL WIRING REPAIR. Preferred repair methods consist of replacing wires, terminals, connectors, etc.,
rather than splicing wires, bending ends to and from terminals, and other makeshift procedures; although the latter may
be appropriate for emergency field repairs. Determine the proper size and length of wire, or the terminal, or connector to
be used for replacement by referring to table 4-4, Wire List, and to the wiring diagram.
a. Crimping Terminals. To install a terminal on the end of a wire, strip 1/4 - 1/2 inch (0.6 - 1.3 cm) of insulation from
the end of the wire, apply a 1-inch piece of heat-shrink tubing (if the terminals are of the uninsulated type), and insert wire
end into the shank of the terminal. Crimp the shank, and install heat-shrink tubing, if necessary.
b. Insulation Joints. The preferred method of insulating electrical joints is by the use of heat-shrink tubing. To apply,
cut a piece of heat-shrink tubing of suitable diameter to a 1-inch length for covering joints at terminals or connectors, or to
a length about 1/2 inch (1.3 cm) longer than the joint to be insulated, and slide the tubing over the wire before making the
joint. After the joint is made, slide the tubing so that it covers the joint, and shrink in place with moderate heat.
