TM 5-3805-261-342-3.GENERAL MAINTENANCE INFORMATION. (cont)m.ElectricalSystemComponentsandWiring. (cont)(5)Cleaning electrical connectors. (cont)(c)Rinse away loose corrosion, dirt and other contamination from the connector and pins withcleaning compound MIL-C-81302. Hold connector pointed slightly downward, if possible, while spraying cleaningcompound MIL-C-81302 into socket openings.(d)Wipe excess spray with a lint-free cloth.(e)Do steps 2 thru 4 again, if necessary, to remove corrosion.(f)Threaded holes in metal must be thoroughly clean when sealing compounds are used to lockscrews in place. Clean old sealing compound out of threads with tap and tap wrench. Blow loose particles out of holes withcompressed air and clean threads with cleaning compound MIL-C-81302 and acid-swabbing brush. Let holes dry beforeputting in screws.(g)When cleaning and inspecting ground points, take off ground contact from mounting point. Cleanground point bolt, nut and contact with cleaning compound MIL-C-81302 and acid-swabbing brush. If corrosion is present,clean with wire brush and abrasive cloth. Look at all parts for cracks, looseness or stripped threads. Replace damaged orcrossthreaded screws and nuts. Check for torn or stretched gaskets and leaks. Turn in bad parts. Be sure to tighten allnuts when mounting ground contacts.(h)Rub corrosion off connector contacts and other parts with pencil eraser. Remove rust by scraping,wire brushing or both. If rust damage is too great or on small thin parts that would be weakened by rust, you may need toreplace the part. Find the cause of the rust and correct the problem.(6)Inspecting connectors.(a)Disconnect the electrical connector to be inspected.NOTEUse a good light source to look at electrical contacts.(b)Look for white powdery or granular material anywhere on the outer or inner surfaces of theconnector and receptacle. Look at the male and female sockets for signs of blue-green discoloration at the base of thepins or sockets. Clean off surface corrosion before assembling. Electrical contacts corroded badly enough to destroy theouter metal coating should be replaced. Any part corroded badly enough to weaken it should be replaced.(c)Look for bent, broken, missing or pushed-in contacts. Straighten bent pins with long, round-nosedpliers. Other damage should be repaired or parts replaced.2-16
