The red alternator wire is 10 gauge and is protected by a 14 gauge fuse
link.

Normally a fuse link is 2 sizes smaller than the circuit it protects.

The fat size is just soft rubber insulation that won't melt like plastic
when the link gets hot.

You can buy fuse link wire in bulk to replace one if needed. Be aware
that you have to use crimp connectors on the ends and it needs to be the
same length as the stock one or about 8" long. Solder will ruin the
thermal properties of the link.

If you replace a fuse link with regular wire or with heavier wire, you
will cause a fire to start when whatever blew the first link goes nuts
again.
