Add-On Electrical Equipment
Notice:Do not add anything electrical to the
vehicle unless you check with your dealer/retailer
first. Some electrical equipment can damage
the vehicle and the damage would not be covered
by the vehicle’s warranty. Some add-on electrical
equipment can keep other components from
working as they should.
Add-on equipment can drain the vehicle battery, even if
the vehicle is not operating.
The vehicle has an airbag system. Before attempting to
add anything electrical to the vehicle, seeServicing
Your Airbag-Equipped Vehicle on page 1-58.
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 several gauge
sizes smaller than the circuit it protects. It will melt in an
overload situation, opening the circuit.
The starter and other circuits have fusible links. The size
is printed on the insulation. If the insulation is burned
beyond recognition, consult your dealer/retailer 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.
Some examples of circuits with fusible links are the
hydraulic brake booster motor feed circuit, the generator
output circuit, and the intake heater feed circuit in
vehicles with a diesel engine.
