electrical System
The electrical system includes mounting 7-way
receptacle, wiring, lamps, and various other
accessories. Regular inspection of the system is
necessary for the safe operation of the vehicle.
The electrical system of your Wabash National
trailer meets or exceeds all federal and state
requirements in effect at the time of manufacture.
NOTE:
Wabash National’s standard front marker
lights are PC-rated (visible over 180 degrees) and
mounted for protection from damage on the trailer’s
sides. This mounting arrangement complies with
required regulations and satisfies the requirement
for lights on the front. (See FMVSS 49 CFR Section
571.108.)
For the electrical system to operate properly, the
tractor must supply a reliable power source of 12
volts DC from the tractor pig-tail to the trailer 7-way
receptacle. The 7-way receptacle is equipped with
a hinged cover that locks the connection in place
and protects it from exposure to dirt and water
when not in use.
Wiring for most Wabash National trailers is shown
in the illustration on Page 16.
To achieve the best performance and extend the
life of the trailer lighting:
• Keep all lamps and reflectors clean for optimum
visibility and safety.
• Never use a test probe to pierce wire insulation.
Punctures to the wire jacket will allow moisture
to collect on the wire strands, corroding critical
connections.
• Regularly inspect your wiring junctions and
grounds for poor connections and/or corrosion.
Clean and grease them with a dielectric grease as
necessary.
• Regularly inspect your wiring harness for damage
and/or unsupported wiring.
• When maintaining the electrical system, make
sure only original components are used.
CAUTION:
Always turn your trailer lights off while positioned at
a loading dock.
WaRNING:
Never operate the trailer with any nonfunctioning light.
