- Service the removed contacts as required. Refer to the ""Contact Crimp Procedure" " section in this manual for contact crimping procedures.
Contact Crimp Procedure
To ensure proper electrical performance, contacts must be crimped using the CH1-1155 Crimping Tool (order separately) and the following procedure. DO NOT solder the wires into the contacts.
- Cut the end of the 14, 16, or 18 AWG wire square and clean.
- Strip 6.4 to 7.0 mm (.25 to .31 in) of insulation from the wire. Do not to cut or nick the copper wire strands. A properly stripped wire will touch the bottom of crimp barrel (17), with the wire visible through inspection hole (18). The wire insulation will be 1.5 mm (.06 in) from the end of the contact.
- Make sure wire selector gauge (20) on CH1-1155 Crimp Tool (19) is set to the wire size being crimped. If the wire selector gauge is properly set, proceed to Step 4. If the selector gauge setting does not match the wire size being crimped, proceed as follows.
- Remove lock clip (21) .
- Raise selector knob (22) and rotate until the arrow is aligned with the wire size to be crimped.
- Lower the selector knob and insert the lock clip.
Note: On the socket contact, the stripped wire is inserted into the end with inspection hole (18).
