1. Temporary Wiring Harness Repair
The following method to repair wiring is a temporary
expedient only. Wiring should be replaced as soon
as possible. Do not attempt to repair the wire on any
system sensors as these are sealed and should only
be replaced with a new component.
NOTE: When conducting a cable repair it is important that
only RESIN CORED SOLDER is used. Use of other types
of solder may result in further cable damage.
2. To carry out a temporary repair, proceed as follows:-
Locate damaged portion of cable then cut away outer
protective cover on both sides of the damaged area.
3. Peel back the cable from both ends of the damaged
area and carefully cut away the inner cable cover at
the damaged area and strip about 13 mm (1/2 in) of
insulation from the wires. Do not cut away any wire
strands.
Using a suitable solvent, clean about 2 in (50 mm)
from each cover end. Clean the grey cable cover and
the individual leads.
Twist two bare leads together for each damaged
lead, being careful to match wire colours, then sol-
der the leads using resin cored solder. Tape each
repaired lead with vinyl insulation tape.
4. Wind a layer of vinyl insulation tape up to the grey
cable cover at each end of the repair section. Make
a paper trough, then apply silicon rubber compound
(non hardening sealant) over the repaired section up
to the cover ends. Sufficient sealant must be used to
fill the ends of the cut away area.
