Add-On Electrical Equipment
Notice: Do not add anything electrical to your
vehicle unless you check with your dealer
first. Some electrical equipment can damage
your vehicle and the damage would not
be covered by your warranty. Some add-on
electrical equipment can keep other
components from working as they should.
Headlamp Wiring
The headlamp wiring is protected by a circuit
breaker in the light switch. An electrical overload
will cause the lights to go on and off, or in
some cases to remain off. If this happens, have
your headlamp wiring checked right away.
Windshield Wiper Fuses
The windshield wiper motor is protected by a
circuit breaker inside the motor and a circuit
breaker or fuse in the fuse block. If the motor
overheats, the wipers will stop until the motor
cools. If the overload is caused by an electrical
problem, be sure to get it fixed.
Fusible Links
A fusible link is a short piece of wire that is
covered by an insulated cover. It is several gage
sizes smaller than the circuit it protects. It will
melt in an overload situation, opening the circuit.
Your starter and other circuits have these
fusible links. The size is printed on the insulation.
If the insulation is burned beyond recognition,
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.
