Slide the gasket to the clamp. Tin the inner conductor with 60-40 resin core solder. Slide the inner contact over the cable end until flush with the inner insulator. Solder the contact to the  conductor. Slip the connector jack body over the end  of the cable and secure it with the nut and washer.

Although an installation may appear to be a  simple procedure, many avionics troubles are attributed to careless oversights during equipment replacement. Loose  cable connections, switched cable terminations, improper  bonding, worn shock mounts, improper safety wiring, and  failure to perform an operational check after installation may  result in poor performance or inoperative avionics. 11-77
