Complete the ratchet cycle before judging the connection
Match the Die
Align the terminal color and AWG with the correct die cavity.
Pre-Crimp Lock
Close the handles until the jaws hold the connector without crushing it.
Insert & Cycle
Insert the wire fully, then complete the ratchet cycle until release.
Pull Test
Confirm the wire is secure before shrinking and sealing the sleeve.
Seal after the pull test
Apply even heat without an open flame
The Mini Heat Gun delivers controlled heat from the center outward so the tubing contracts evenly and the internal adhesive forms a visible moisture seal.
