I don't see that he's not crimping the insulation. The proper tool will crimp both the insulation and the conductor at the same time. What's important is to strip the wire back the appropriate length, and then to insert the wire into the terminal the proper distance.Hi,
Do you agree that this wire has been crimped incorrectly with a JST-XH crimp?
..at 3:07 you can see he didnt crimp the end of the insulation of the wire....so his crimping lacks strain relief, and is more likely to see his wire snap at the crimp?
