An article from Second Chance Garage titled “Electrical Connections: The Importance of Soldering” gives a visual example of success.
Page one shows the strands of a wire pinched down in a connector. Most of the strands, but not all, make an electrical connection.
This is the way most folks do it, pinch the wire tight and be on our way. But the wire gives out, eventually unable to carry enough load because a third of the strands were unused.
Page two shows the same wire properly connected with solder. All strands are used to make an electrical connection. The wire is reliable and trouble free.
Refocusing for success means tightening trouble spots until the juice flows in our projects again.
