In addition to the main fuse wire (Fusible Link) in the engine compartment, there is a main fuse box under the dashboard.

Late Ute
Utes from 1982 feature rectangular fuses. Also eliminates the plug-in connectors on the back of the fuse box, which was a problem spot in older 1200s (now the harness wires go directly to the individual fuses, whereas formerly they ended at large spade connectors).

The "ENGINE CONTROL" fuse was also used by B310 and other 1980s Datsuns. It is the main Ignition-switched feed for the engine harness. Feeds the vacuum cut, fuel cut, and auto-choke relay.

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.
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 leading to overheating and partial melting:
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 NEG terminal
- Remove all the wires from the fuse box (take a photo first, or write down carefully which 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
- Dry thoroughly, or let dry overnight
- Put a little dielectric greaseᴳ (a LITTLE not a LOT) on each copper terminal (front and back of fuse box). This will help prevent moisture corrosion
