Terminal Repair Procedure 

Follow the steps below in order to repair Micro 64 connector terminals. 

The Micro 64 connectors have small terminals that are difficult to handle and hold when crimping. In order to 
aid the technician when crimping these terminals, a new crimping tool was developed. The J 38125-64 (M jaw) 
was developed to crimp Micro 64 terminals. The J 38125-64 crimping tool has a terminal holding block that 
will hold the terminal in place while the terminal is being crimped. The J 38125-64 crimping tool is also 
designed to crimp both the wire and the insulation at the same time. 

After the terminal is removed from the connector perform the following procedure in order to repair Micro 64 
terminals. 

IMPORTANT: After cutting the damaged terminal from the wire, determine if the remaining

wire is long enough to reach the connector without putting a strain on the wire. 
If the wire is not long enough, splice a small length of the same gauge wire to 
the existing wire, then crimp the new terminal on the added wire.
