Decent Terminal Crimper

There are 2 kinds of crimp die. One shaped for insulated terminals sort of shaped like this () and one shaped for non insulated terminal sort of shaped like this >] . Ratcheting mechinism is meant to ensure there is no under crimp.
It won't open until the tool is fully cycled. They usually have an escape mechanism in the event the crimp is in the wrong die and can't be fully cycled.

A couple of things could damage the insulator. The wrong crimp die shape, the wrong size die. The shrink tube idea provides some mechanical transition from the crimped wires to the wire insulation. The end game is to have more than just the wire strands involved in the mechanical connection.

This sort of is like an oil thread. :)
 
I wired up an Aux fuse block on a friends VFR yesterday. I tried the crimp with the insulator in place and with the insulator removed. The crimps were much tighter with the insulator removed. Also, I could use different colored heat shrink just to mess with my anal retentive friend!.
 
klien, greenlee, and G&B make hand tools that come in around 40 or so. imho few home hobbists can justify buying a d.action crimper. the cheaper hand crimpers do take a bit more hand pressusre. i do some as part of my work, and have enjoyed getting by with the cheap ones.

Having crimped many a terminal, in all sizes, and having used many a tool, I have had the best use from a pair of Klein crimpers. They are very well made, but reasonably priced eletrician's tools, some of which are sold at Lowe's.

And use the Correct Klein crimpers with crimp and seal terminal ends.

After you crimp, use a bic lighter or mini torch to heat the insulator untill the sealing glue melts and oozes out for a water proof seal.
