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.

Always use replacements of the same electrical capacity as the original, available from your dealer.

All 1971-77 models have only one fusible link which is located in-line at the positive battery terminal. Main circuit protection is for the ignition system.

All 1978-85 models have three fusible links, all of which are located in-line at the battery. Circuits protected include the ignition circuit, the headlight circuit and the heater circuit.
