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

Contents

Overview

23310.jpg

USA 1972 Owners manual (see pages 35 for fuse information):


00_cover.jpg 35.jpg

If a fuse needs to be replaced, refer to the specifications listed on the fuse box cover.

Fuses
B110 uses the standard cylindrical fuses used by all cars until around 1980. The numbers are:


IG: Ignition Switch Circuit (only HOT when key is in IGN position)

  • 15 AMP Wiper, Washer, Heater
  • 10 AMP Meter, Reverse Lights, Alternator Regulator

Battery/Alternator Circuit (always HOT)

  • 15 AMP Head Lamp
  • 10 AMP Park lights, Tail lights
  • 15 AMP Radio, Cigarette lighter, Room lamp
  • 15 AMP Horn, Stop lights, Hazard lights

There are also two empty holes in the fuse box to hold two spare fuses.

Wiring

The wiring harness has individual connectors to the Fuse Box:

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. It has a special non-flammable coating, and is typically 4 wire sizes smaller than the main feed wire.


WARNING: Do not replace fusible link with a solid wire, or a regular fuse -- you risk burning up the entire wiring system ... see Wiring#Main Wiring

The white wire here has been cut from the Postive battery cable:

Both green wires are the same. Top: New, Bottom: old and faded

  • 25442-H2500
  • replaces 25442-H1100 LINK-FUSIBLE,TYPE C replaced
    • part number 25442-H1100 originally for B110
    • part number 25442-H2500 for B210
  • Spec: FUL 0.5mm2 [0.5 square mm]

MAD Fusible Link information - why Fusible Link is better than a Fuse

Aftermarket

Use a "FUL 0.5mm2" fuse-link.

  • 20 gauge: 0.5 square mm
  • 18 gauge: 0.8 square mm *TOO BIG FOR DATSUN 1200*
  • 16 gauge: 1.0 square mm *TOO BIG FOR DATSUN 1200*
  • 14 gauge: 2.0 square mm *TOO BIG FOR DATSUN 1200*


Universal Fusible Link - 20 gauge

You can use Ford, GM or Chrysler style too:

Discussion: will this Fusible link suit ?
