Fusible Link

The Fusible Link ("Main Fuse") connects to the POS battery terminal about six inches from the battery. The fusible link is a special length of wiring that will melt if its rating is exceeded and is there to stop the electrics if the car is drawing too much power, like an open short circuit.

See main article: Fusible Link

Cleaning

If your fuse box gets HOT or starts melting (but the fuse does not blow), then remove the fuse box and CLEAN it. Soak it in vinegar for 10 minutes.

Or if you are getting electrical equipment not working, clean the fuse box.

Why? Dirty connections cause undue resistance, eventually leaking to this:

The reason that fuse lead is getting hot is because of resistance. This is pretty common with old-styled glass fuse boxes. You get resistance at either the fuse itself, or the connection between the fuse and the terminal - along with whatever other resistance is present in the wiring. The corrosion is at the fuse box connections, which is why it gets hot, and why it melts.

Disconnect the battery
Remove all the wires from the fuse box (take a photo first, or write down carefully wire goes where). Mark each wire with a piece of tape.
Take the Fuse Box in the house and soak it. Fill a small bowl with distilled white vinegar from the grocery store. Soak for 10 minutes.
Rinse with water with a little Baking Soda mixed in -- this will nuetralize the acid from the vinegar. Then rinse with plain water
Let dry thoroughly/overnight
Put a little dielectric grease (a LITTLE not a LOT) on each copper terminal (front and back of fuse box). This will help prevent moisture corrosion
