b. Remove the feeder end connector, molded gas plug (or barbed fitting), cable handle nut, plastic

NOTE: In order to remove the cable handle nut, the tail of the connector cover must be depressed and the cable handle nut rotated 1/4 turn counterclock- wise as viewed from the feeder end.

c. Remove incoming connector from cable by unscrewing connector nut from incoming connec- tor. If the cable inner tube is difficult to remove from the connector assembly, carefully slit it lengthwise with a knife up to the brass connector.

d.Move the cable boot and cable handle toward the middle of the cable past the damaged section.

e.Cut off the damaged section of cable and strip off the outer jacket as shown in Figure 2. Be careful not to cut the insulation on the control wires while stripping jacket. Strip the red and white control leads 1/4 inch (6.4 mm) from the end and crimp a new S19492-1 terminal to each lead.

NOTE: The cable contains three control leads. Any two control leads can be used, provided the two colors used are the same at both ends. The extra lead is a spare that can be used if one of the other leads breaks.
