54–01 Trailer Cable Inspection
and Cleaning
1. Inspect the cables for cuts, abrasion, or other
damage. If internal wiring is exposed, replace the
cables.
2. Disconnect the trailer electrical cables from the
sockets at the cab.
3. Inspect the cables and sockets for evidence of
corrosion, and clean as necessary. If a socket is
too badly corroded to clean, replace it. If
corrosion has gotten into the wires and
connectors inside the socket, replace the cable.
IMPORTANT: If using a spray cleaner to remove
corrosion, be careful to protect any surrounding
painted surfaces. Follow appropriate safety
measures.
4. Coat the inside of the sockets with a lithium-
based dielectric grease such as Lubriplate FLP
DS–ES.
5. Connect the cables.
54–02 Electrical Component
Inspection
1. Park the vehicle on a level surface, shut down
the vehicle, and set the parking brake. Chock the
tires.
2. Disconnect the batteries.
3. Inspect the condition of the electrical component.
Check for signs of excess dirt/debris build up on
or around component. If exterior cleaning is
needed for a thorough inspection, clean exterior
debris from the component using a dry method
such as a vacuum cleaner or using an electrical
contact cleaner such as CRC QD® Electronic
Cleaner.
4. Check all mounting points for loose, broken, or
missing parts. Component must be securely
mounted. All loose, broken, or missing parts
must be repaired to maintain proper component
function.
5. Inspect the component protective cover for
proper fit and function. Inspect cover for cracks,
broken mounting, missing sealing surfaces,
warped or bulged surfaces. The cover must
prevent moisture and debris from entering the
components protected area. Missing, leaking, or
damaged covers will result in moisture and
debris entering the component and will result in
component failure. When it is determined that a
cover has not properly prevented moisture and
debris from entering the component, the entire
component must be replaced.
6. Inspect the component exterior for signs of
thermal distortion, warping, bulging, discoloration,
amperage related heating, color variance or
shading across component which could be a sign
of internal failure requiring replacement of the
component. The root source causing conditions
of high heat, excess amperage, and/or circuit
overload component failures must be diagnosed
and repaired prior to replacing the component.
7. Inspect component housing sub-assembly clips
and fasteners for correct fit and location and that
component sub-assembly housing seams are
tight and secure. Missing, leaking, or damaged
component housings must be replaced.
8. Check main power cable connections for a clean
and secure fit. Connections should be free of
corrosion, dirt and moisture. Connections should
not have signs of thermal distortion, warping,
discoloration, high amperage heating or
discoloring. If needed, disconnect cables, scrub
and clean as needed using a nylon brush. Clean
debris with vacuum or electrical contact cleaner
such as CRC QD® Electronic Cleaner, inspect
terminals and mating contact terminal plating. If
the terminal plating exhibits signs of
unrecoverable corrosion, the component and
terminal will need replaced. Indications of
unrecoverable corrosion on terminal plating are:
•
Heavy staining that cannot be cleaned off
with nylon brush or contact cleaner;
•
erosion and pitting on terminal plating
causing uneven surfaces; or
•
discoloration caused by outer layer of
plating being removed by corrosion or wear
exposing the under layer material of
terminal.
9. Check all electrical connectors for correct fit and
that the connector locking tabs are in place and
will hold the connector firmly into the component.
Inspect connector terminals for signs of
corrosion, thermal distortion, warping,
