I guess I called the part the wrong name. I am looking to replace a fusible link. Anyone done this or know how or at least know where to get a new one? From other posts it sounds kind of tricky. Thanks for the help

If you find where you can get new ones let me know, I would go to the j/y an get some then solder it in good for a replacement.

Fusible link wire is sold by wire gage (the fuse link wire should be four gages smaller - four numbers larger - than the wire it's protecting. Therefore, a 12AWG circuit is protected by a 16AWG fusible linke) either as short prepack lengths or in bulk at better parts houses. Prepacks would be in the "Help!" section, while bulk stuff will be behind the counter.
Fuse link wire is typically colour-coded by gage size.
Replacing a blown segment is simple - you'll need whatever size ring lug is on the end that connects to distribution (most often 3/8",) and a "step-down butt splice" or a very good twist/tape technique (I don't recomment soldering fusible link wire - it's made from a low-melting alloy. Cold joining is better.) Strip and crimp like regular wire, make sure the final connexions are sealed (I like heat shrink tube for this, or heat-shrinkable connectors.) Make sure you join the new fusible link to actual wire, and not to the stub of the old fusible link!
Replacing fusible links is quite simple - since it's handled just like any other wire-splicing job. Although, when I have to replace a fusible link, I'll usually put on a set of bullet taps or shrouded spade-type quick-connects - this allows for easier joining of wire of dissimilar sizes, and saves me having to cut harness wire if I have to replace it again (always assume the next poor schmuck to work on something will be you, and you'll have a box of matches, a Swiss Army Knife, and a rock... Redesign accordingly.)
