TM 5-3805-261-202-4.GENERAL MAINTENANCE INFORMATION.m.ElectricalSystemComponentsandWiring.(11) Applying Preservatives to Electrical Connectors.WARNINGWater-displacing corrosion preventive compound vapors can be harmful to eyes and lungs. Toavoid injury, keep the corrosion preventive away from heat, wear protective goggles and use in awell-ventilated area.CAUTIONThere are two types of water-displacing corrosion preventive compounds. Care must be used toapply the correct compound. Failure to do so can cause loss of continuity or moisture protection.(a)Pin contacts: Spray an even, thin coat of compound MIL-C-81309 over male pin area of connector.(b)Socket contacts: Hold connector with openings pointed slightly downward, if possible. Spraycompound MIL-C-81309 into socket openings. Wipe off any excess compound with a lint-free cloth.CAUTIONDo not use water-displacing corrosion preventive compound MIL-C-81309 on the external surfaceof an electrical connector. MIL-C-81309 is too light and will not give the protection needed to keepmoisture out of the connector.(c)External surfaces: Spray a thin coat of water-displacing corrosion preventive compound MIL-C-85054 on all external surfaces of the clean connector set. Make sure the area where the connector set comes together iscompletely covered.(12) Installing Electrical Connectors.(a)Look at connectors for broken, missing or pushed-in contact before making any connections. Ifconnector is bad, notify supervisor.(b)When installing connectors on large harnesses, another soldier will be needed to help aline themating ends of the cable. Make sure that contacts and key washers line up. Tighten twist-snap-type connectors until aclick is heard. Tighten screw-on-type connectors until the connector is tight. Tighten ratchet-type connectors until coloredalining marks line up.2-17
