REPAIR PROCEDURES
Step Six: Tape S p l i c e / I n s e r t Terminal
Tape over both the splice clip and the
petroleum jelly to seal out moisture and insu-
late the splice (see Figure 15). If you have
replaced a lead, do not tape over the terminal
crimp area but insert the lead into the connec-
tor bodv.

SHIELDED CABLE
Twisted/shielded cable is sometimes used to
protect wiring from electrical noise (stray sig-
nals). For example, two-conductor cable of this
construction is used between the ECM and the
distributor. See Figure 16 for a breakdown of
twisted/shielded cable construction.
Step One: Remove Outer Jacket
Remove the outer jacket and discard it. Be
careful to avoid cutting into the drain wire or
the mylar tape.
Step T w o : Unwrap the Tape
Unwrap the aluminum/mylar tape, but do
not remove it. The tape will be used to rewrap
the twisted conductors after the splices have
been made.
Step Three: Prepare the Splice
Untwist the conductors. Then, prepare the
splice by following the splicing instructions
for copper wire presented earlier. Remember to
stagger splices to avoid shorts (see Figure 17).

Clip (Aluminum Wire)
Step Four: Re-Assemble the Cable
After you have spliced and taped each wire,
rewrap the conductors with the mylar tape. Be
careful to avoid wrapping the drain wire in the
tape.
Next, splice the drain wire following the
splicing instructions for copper wire. Then,
wrap the drain wire around the conductors and
mylar tape (see Figure 18).
Step Five: Tape the Cable
Tape over the entire cable using a winding
motion (see Figure 19). This tape will replace
the section of the jacket you removed to make
the repair.
