Electrical solderless or soldered connectors

Also, I seem to remember reading something regarding the chemical makeup of the solder reacting with the stranded wire and corroding. Maybe the acid in the solder? I've taken apart may soldered connections that were green with corrosion.

Cool, this thread is still going! Yeah moisture got into that connection turning it green. Here's Scotty showing us how to do it right. Rev up your engines! lol.
