GENERAL MAINTENANCE INFORMATION. (cont)
Electrical System Components and Wiring. (cont)
Tighten connectors by hand only.
Wipe the outer surface of the connector with a lint-free cloth dampened with cleaning compound.
(13) Connecting and Disconnecting Connectors.
Look for broken, bent or missing pins when disconnecting or connecting receptacles and
connectors. If you find any bent pins, tell your supervisor. Look at harnesses for cuts, kinks or torn or burned insulation. If
insulation is bad, replace harness.
If connectors cannot be removed by hand, use conduit-style, slip-joint pliers with plastic jaw inserts
to remove them. When installing connectors on larger harnesses, another soldier will be needed to help aline the mating
ends of the cable. Make sure that pins and keyways line up. Tighten twist-snap-type connectors by hand only until a click
is heard. Tighten the screw-on-type connectors by hand only until the connector is tight.
Put protective caps and plugs on all connectors when they are taken to keep pins from being
damaged and to keep out dirt, dust or grease. When connectors are being put on, take off all caps and plugs.
(14) Harness Routing.
Before removing harnesses that require being placed over and under components during
installation, the routing must be identified during removal to insure proper installation.
If harness routing can be reached, route and tag twine where harness branches are laying before
pulling harness out of place for removal.
If harness routing cannot be reached, tie twine to ends of harness branches. Twine should be
longer than harness. Pull harness out until twine can be tagged and untied from harness branches.
Install harness by either feeding harness branches through where twine was placed, or tie tagged
twine to mating harness branch and pull harness into place with twine. Remove twine.
Be sure that routed harness and branches are not twisted or sticking up where they can rub the
opposite frame when the vehicle is being articulated.
