IF he had two bad crimps there are more, he needs to check everything and get them up to spec.

It makes a flat crimp and does not hold well. Instead use the non-insulated terminal part. It makes a V crimp deeper into the wire and holds much better. You can even double crimp if you wish. I have been using this method in marine work for 40 years with no problems.

It will crimp the wire and do an insulation crimp to relieve the strain on the wire crimp.
Most also have a wire stripper, so no nicking of wire strands.

Finally, a strain relief of the wire should be made to a solid structure , [ adel clamp ], within 2 inches of the terminal, to keep vibration from fatigue failing the wire .
Properly crimped and strain relieved wires should last more than 20 years.!
