| + | * Next, crimp the terminal. A good mechanic connection is critical before it is soldered. Solder should not be used to support a connection just to bond it. | ||
* Next, solder the wire to the ring terminal, "wicking " the solder up into the terminal sleeve, until it is filled, smooth, and shiny silver. | * Next, solder the wire to the ring terminal, "wicking " the solder up into the terminal sleeve, until it is filled, smooth, and shiny silver. | ||

* When cool, slide the colored tubing (for example: red) over the first, and flush with the ring end, and shrink it down. Net result is you have a terminal with a red marker and about a 1/4 trailer behind it. Looks professional, and lasts forever. | * When cool, slide the colored tubing (for example: red) over the first, and flush with the ring end, and shrink it down.

Even on crimp terminals, solder AND crimp. | Even on crimp terminals, solder AND crimp. | ||
