Proper use of old style hand crimpers

the reason option B is correct for a non insulated terminal (and is not correct for the insulated terminal as shown-therefore all 3 options A,B, and C are incorrect) is that if you put the tooth on the seam, it will divide the copper wire strands roughly in half and also smash or even possibly break the wire strands directly beneath the tooth. Also, you will probably be left with some wire strands located directly beneath the tooth with no contact except for maybe the plastic you distorted and punched a hole in for water, dirt, etc. to enter. The seam is only to allow the metal "tube" portion to deform from the tooth stress applied on the side opposite to the seam. I see about 100 connections in the background of the pic :eek:
