Nissan Z - ZX 1970-1988 Repair Guide

Fusible Links

Print

See Figures 1, 2 and 3

The fusible links are protective devices used in the electrical circuits. When current increases beyond the amperage the link is designed to withstand, the fusible metal of the link melts, breaking the circuit and preventing further damage to other components and wiring. Whenever a fusible link has melted because of a short circuit, correct the cause before installing a new link.


WARNING
Always use replacements of the same electrical capacity as the original, available from your dealer. Replacements of a different electrical value will not provide adequate system protection.

All 280 and 300 ZX models fusible links are located in a case next to the battery in the engine compartment. Circuits protected include the electronic fuel injection circuit, the ignition circuit, the ignition supply to the fuse box, the accessory supply to the fuse box and the headlight circuit.

The 280 Z fusible links are located on the relay bracket on the inner right fender in front of the battery. The fuel injection fusible link is connected between the battery positive cable and the fuel injection harness.

On the 260 Z, the fusible link box is located on the firewall on the right side of the engine compartment. These links protect the alternator and the starter.

On the 240 Z, the links are located at the starter motor and alternator.

Fusible links are typically color coded (as are fuses), based on their amperage rating.
