Cables
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 com-
pound,
NSN
and scrubbing with that short-bristled
acid swabbing brush. The compound
also displaces water, which should
help prevent further corrosion down
the road.
When connecting cables, make sure
the pins line up with the receptacle.
Bent or broken pins are a sure
cable killer.
Gladhands
Check the rubber grommets inside the
gladhands for wear and tear. The rubber can
dry out and crack, letting in moisture.
Use NSN 5330-00-172-1919 to order a
replacement grommet.
