No Drag, Cable’s Glad
Be sure to hook up the cable so it
doesn’t drag. Dragging the cable as your
truck pulls the trailer wears out the cable
and can set it on fre.
When connecting cables, make sure the
pins line up with the receptacle. Bent or
broken pins are a sure cable killer.
The cable hooks up the brake lights and
signal lights, so it’s an honest mistake to
stop connecting when you see the lights
come on. But when you see the lights,
keep pushing to ensure a good hook-up.
That should prevent a dragging cable.
Remember, when the cable or connector
goes bad, you have to replace the whole
cable assembly.
Before Connecting
BeFore installing cables, take a close look at the
connectors and receptacles For dirt and corrosion.
Loose dirt can usually be blown out with the help
oF an air hose.
Stubborn
dirt
can be
a
little
tougher. Try clipping oFF all but about
1
/
2
inch oF the bristles on an acid
swabbing brush, NSN 7920-00-514-
2417. The shorter bristles make them
stiFF enough to brush dirt out oF the
connector and around the outside oF
the receptacle.
To remove corrosion, try spraying
a light coat oF corrosion preventive
compound, NSN 8030-00-546-8637,
and scrubbing with that short-bristled
acid swabbing brush. The compound
also displaces water, which should
help prevent Further corrosion down
the road.
Lunette Trailers…
if you don’t do your
job during hookup
and maintenance, your
lunette trailer’s
intervehicular cables
won’t do theirs.
That means
problems
with
the trailer’s
lights.
Dragging cable wears it out!
Check cable connector for dirt and corrosion…
Clean out
dirt with
modiFed
brush
…and check receptacle, too!
I pulled
you over
because you
were driving
without
brake
lights.
{sniff

that’s
because my
cable is
worn
out
from
dragging…
please
don’t give me
a ticket!
