Connector/Terminal Repairs
B.
Terminal Removal
1. Remove the locking bar(s) from front of the connector (Figure E–1, View A).
2. Move the appropriate terminal finger slightly up or down to release the desired terminal and pull
on the wire to remove the terminal from the back of the connector.
3. If replacing the terminal, cut the wire between the core and insulation crimp to minimize wire loss.
C.
Terminal Crimping
1. Carefully strip insulation 4 mm ± 0.5 mm (0.16 ± 0.02 inch). Automatic Wire Stripper J 35615 will
remove insulation and crimp from old terminal without damaging the wire, unless the insulation
crimp is overtight.
2. Insert a terminal into Crimp Nest No. 2 of crimping tool J 38687 (Figure E–1, View B).
3. Properly position the stripped wire in the terminal and squeeze the handles of the crimping tool
until the ratchet mechanism releases.
4. Insert the newly crimped terminal back into its cavity and push until the terminal finger “locks”
into place.
5. Reinsert the locking bar(s) into the front of the connector.
D.
Deletion of RSI Jumper Wire
1. Follow Steps 1 and 2 of Paragraph B (Terminal Removal) above.
2. Insert cavity plugs in cavities 2 and 3.
