Hand Crimp Tool
Using the J 38125-8 splice crimp tool, position the splice sleeve in the proper color nest of the hand crimp tool. Place the splice sleeve in the nest
so that the crimp falls midway between the end of the barrel and the stop.
Seal Splice Sequence
The sleeve has a stop in the middle of the barrel to prevent the wire from going further. Close the hand crimper handles slightly to hold the splice
sleeve firmly in the proper nest.
Step 5: Insert Wires into Splice Sleeve and Crimp
Insert the wire into the splice sleeve until it hits the barrel stop and close the handles of the J 38125-8 crimper tightly until the crimper handles
open when released. The crimper handles will not open until the proper amount of pressure is applied to the splice sleeve. Repeat steps 4 and 5 for
opposite end of the splice.
Step 6: Shrink the Insulation Around the Splice
Using the Ultratorch J 38125-5 (follow instructions that accompany Ultratorch), apply heat where the barrel is crimped. Gradually move the heat
barrel to the open end of the tubing, shrinking the tubing completely as the heat is moved along the insulation. A small amount of sealant will come
out of the end of the tubing when sufficient shrinking is achieved.
Splicing Copper Wire Using Splice Clips
Splice clips are included in the J 38125-A Terminal Repair Kit. The splice clip is a general purpose wire repair device. It may not be acceptable for
applications having special requirements such as moisture sealing.
Step 1: Open the Harness
If the harness is taped, remove the tape. To avoid wire insulation damage, use a sewing "seam ripper" to cut open the harness (available from
sewing supply stores). If the harness has a black plastic conduit, simply pull out the desired wire.
Step 2: Cut the Wire
Begin by cutting as little wire off the harness as possible. You may need the extra length of the wire later if you decide to cut more wire off to
change the location of a splice. You may have to adjust splice locations to make certain that each splice is at least 40 mm (1.5 in.) away from other
splices, harness branches or connectors.
