Fusible Links
A fusible link is a short piece of wire several gage sizes
smaller than the circuit it protects. It will melt in an
overload situation, opening the circuit.
Your ammeter and battery to hydraulic brake control
circuits have these fusible links. Fusible links for the
ammeter are located at the starter and the generator.
The size is printed on the insulation. If the size of the
insulation cannot be seen, consult your GM dealer for
the proper size. Replace a fusible link with one of the
same size and insulation type. Fusible link insulation is a
special purpose high temperature material.
Vehicles with a diesel engine also have a fusible link for
the intake heater feed circuit. Should an electrical short
occur, the fusible link will open and prevent damage to
the major harness.
