Practical Crimping Mistakes Guide
A beginner-friendly guide to the crimping mistakes that weaken wire connections: wrong connector size, poor strip length, shallow insertion, under-crimping, and pre-tinning.
Match connector, wire gauge, and die.
Too little strip length weakens the crimp.
Too much strip exposes copper and short-circuit risk.
Insert the wire fully before crimping.
Use a ratcheting crimper for repeat pressure.
Pull-test every finished crimp.
Do not pre-tin stranded wire.
Replace any crimp that moves, cracks, or exposes copper.
Use this guide before choosing terminals or starting a repair, then return to the kit list with the right wire gauge and connector type in mind.
