(1) After determining that a wire is open or
shorted, through the use of test equipment, disconnect
faulty wire at both ends. This is accomplished by pulling
connections apart.
(2) Attach a wire of approximately the same
diameter and several feet longer to one end of the faulty
wire. Tape the splice so that no sharp protrusions exist.
(3) Pull the faulty wire through the conduit
until the opposite end is seen.
(4) Attach a new wire to "leader strip" and
pull back through conduit.
(5) If damaged wire is severed, cutting half,
pick out a neighboring complete wire, tape both wires to
"leader, strip" and repeat above process.
(6) After installation of new wire(s) be sure
that wire numbers match.
