ELECTRICAL GENERAL MAINTENANCE INSTRUCTIONS - CONTINUED
ELECTRICAL SYSTEM COMPONENTS AND WIRING - CONTINUED
Removing Electrical Connectors.
Before removing any component of electrical system, ensure VEHICLE MASTER POWER switch is set to
OFF. You can get electrical burns if power is on.
Do not use pliers without plastic jaw inserts on electrical connectors. Unprotected pliers will damage the
outer plating of the connector. This will expose the metal beneath and cause corrosion.
Dry the outside surface of electrical connectors and receptacles with a lint-free cloth before loosening them for dis-
assembly. Moisture can be present from rain, snow, washing or dew.
If connectors cannot be removed by hand, use conduit-style, slip-joint pliers with plastic jaw inserts to loosen
them. Finish removal by hand. Straighten any bent contacts with long, round-nosed pliers. When installing connec-
tors on larger harnesses, use assistance to align the mating ends of the cable. Ensure that contacts and keyways line
up. Tighten twist-snap-type connectors until a click is heard. Tighten screw-on-type connectors until ratchet noise
is heard to indicate that connectors are tight.
Put a protective cap or cover over any electrical connector that is left uncovered. Cover connectors on any item
being moved to or from the vehicle. Take off covers when connectors are put back.
Look at connectors for broken, missing or pushed-in contacts before making any connections. If a connector is
bad, repair it.
Tighten connectors by hand whenever tools are not called out.
Cleaning Electrical Connectors.
Use gun-type electric heater or open air to dry connector and receptacle.
Solvent cleaning compound MIL-PRF-680 Type III is an environmentally compliant and low toxic
material. However, it may be irritating to the eyes and skin. Use protective gloves and goggles. Use in
well-ventilated areas. Keep away from open flames and other sources of ignition.
Particles blown by compressed air are hazardous. DO NOT exceed 15 psi (103 kPa) nozzle pressure
when drying parts with compressed air. Use a maximum of 30 psi (207 kPa) when cleaning compo-
nents. DO NOT direct compressed air against human skin. Failure to follow this warning may cause
injury or death. Make sure air stream is directed away from user and other personnel in the area. To pre-
vent injury, user must wear protective goggles or face shield.
