(4) Remove the necessary length of the insulation from the end of the wire.
Refer to:
• Table 74 for the insulation removal length for YAV14G82 and YAV14G88 terminal lugs
• Table 75 for the insulation removal length for the other terminal lug part numbers
• Subject 20-00-15 for the insulation removal procedures
Make sure that:
• The conductor does not have nicked or cut strands
• If the insulation is removed by the application of heat, the conductor has not moved from the
center of the wire
• If the insulation is removed by the application of heat, the remaining insulation does not
have blisters or evidence of overheating
• The remaining insulation is not frayed.
(5) If it is specified, fold the conductor back.
(6) Put the conductor of the wire in the crimp barrel of the terminal lug.
Make sure that:
• All of the strands of the conductor are in the crimp barrel
• The maximum distance from the end of the wire insulation of a single wire to the end of the
crimp barrel is 0.12 inch for AWG 10 and smaller, and 0.25 inch for AWG 8 and larger
• The clearance from the end of the conductor is sufficient for the installation of the washer
and the nut.
(7) Crimp the terminal lug.
Make sure that:
• All of the strands of the conductor are in the crimp barrel
• The maximum distance from the end of the wire insulation of a single wire to the end of the
crimp barrel is 0.12 inch for AWG 10 and smaller, and 0.25 inch for AWG 8 and larger
• The clearance from the end of the conductor is sufficient for the installation of the washer
and the nut.
(8) If the crimp tool is a hex type tool and a secondary die is specified, crimp the terminal lug again
with the secondary die.
NOTE: The second crimp removes the flash that is made by the first crimp.
NOTE: The removal of the plating from the terminal lug caused by the second crimp is permitted.
