The one thing that would bother me about removing a scotchlok or similar device from a wire and moving it else where is the way such connectors “tap” into the wire. Unless I am mistaken (and it wouldn’t be the first time) these connectors physically tap into the wire, ie, they pierce the insulation and part of the wire with somesort of blade like devise. As long as the connector is there no problem, but when it is removed the wire that is left is a bit less than the original wire due to the cut out. This would, in my mind effectively reduce the gauge of the wire at that point. Would this cause a “hot spot”? Would this be a place where if flexed the wire would break? This fear is why I much prefer soldering where I can and when I think a connection may be removed in the future.
Well, then that would make two of us paranoid. You also forgot that having pierced the insulation and the removing the clip, you’ve also introduced another opportunity for oxidation.
"The crimp tool is a luxury. You can do just as well with a good pair of slip-joint pliers. Set the slip joint to it’s wider position so that the jaws are more parallel to each other. Don’t worry that the empty pliers won’t close completely when set this way; the thickness of the connector makes up for this. A slow, firm squeeze and you’re all set. "
A crimp is not a luxury, it is a tool designed to do a certain job, and that is to make safe, reliable crimps. They are not expensive. Please NEVER crimps wires in the fashion stated above, especially with higher voltages such as 110VAC. Death and / or fire can occur.
