Some electrical components which require
a large amount of current to operate
use a special switch called a relay. Sinc e these circuits carry a large amount of
current, the thickness of the wire in the ci rcuit is also greater. If this large wire
were connected from the load to the c ontrol switch, the switch would have to
carry the high amperage load and the fair ing or dash would be twice as large to
accommodate the increased size of t he wiring harness. To prevent these
problems, a relay is used.
Relays are composed of a coil and a se t of contacts. When the coil has a
current passed though it, a magnetic fiel d is formed and this field causes the
contacts to move together, completing the circuit. Most relays are normally
open, preventing current from passing thr ough the circuit, but they can take any
electrical form depending on th e job they are intended to do. Relays can be
considered "remote control switches." They allow a smaller current to operate
devices that require higher amperages. W hen a small current operates the coil,
a larger current is allo wed to pass by the contacts. Some common circuits
which may use relays are the horn, headlight s, starter, electric fuel pump and
other high draw circuits.

Fig. 3: Relays are composed of a coil and a switch. These two components are
linked together so that w hen one operates, the other operat es at the same time.
The large wires in the circuit are connect ed from the battery to one side of the
relay switch (B+) and from the opposite side of the re lay switch to the load
(component). Smaller wires are connected from the relay coil to the control
switch for the circuit and from the opposite side of the relay coil to ground
LOAD
Every electrical circuit must include a "load" (something to use the electricity
coming from the source). Without this l oad, the battery would attempt to deliver
its entire power supply from one pole to another. This is called a "short circuit."
All this electricity would take a short cut to ground and cause a great amount of
damage to other components in the circui t by developing a tremendous amount
of heat. This condition could develop suffici ent heat to melt the insulation on all
the surrounding wires and reduce a multiple wire cable to a lump of plastic and
copper.

accidental grounding. It is al
so advisable to include a standard automotive fuse
in any jumper wire. This is commonly referred to as a "fused jumper". By
inserting an in-line fuse holder between a set of test leads, a fused jumper wire
can be used for bypassing open circuits. Use a 5 amp fuse to provide protection
against voltage spikes.
Jumper wires are used primarily to locate open electrical circuits, on either the
ground (—) side of the circuit or on the power (+) side. If an electrical
component fails to operate, connect t he jumper wire between the component
and a good ground. If the component operates only with the jumper installed,
the ground circuit is open. If the ground circuit is good, but the component does
not operate, the circuit between the power feed and component may be open.
By moving the jumper wire successively back from the component toward the
power source, you can isolate the area of the circuit where the open is located.
When the component stops func tioning, or the power is cut off, the open is in
the segment of wire between the jumper and the point previously tested.
You can sometimes connect the jumper wir e directly from the battery to the
"hot" terminal of the component, but firs t make sure the component uses 12
volts in operation. Some electrical components, such as fuel injectors or
sensors, are designed to operate on about 4 to 5 volts, and running 12 volts
directly to these components will cause damage.
TEST LIGHTS

Fig. 1: A 12 volt test light is used to detect the presence of voltage in a circuit
The test light is used to check circuits and components while electrical current is
flowing through them. It is used for volt age and ground tests. To use a 12 volt
test light, connect the ground clip to a good ground and probe wherever
necessary with the pick. The test light will illuminate when voltage is detected.
This does not necessarily mean that 12 volts (or any particular amount of

Headlight adjustment may
be temporarily made using a wall, as described
below, or on the rear of another vehicle. When adjust ed, the lights should not
glare in oncoming car or truck windshi elds, nor should they illuminate the
passenger compartment of vehi cles driving in front of you. These adjustments
are rough and should always be fine-t uned by a repair shop which is equipped
with headlight aiming t ools. Improper adjustments may be both dangerous and
illegal.
For most of the vehicles covered by th is information, horizontal and vertical
aiming of each sealed beam unit is provided by two adjusting screws which
move the retaining ring and adjusting plat e against the tension of a coil spring.
There is no adjustment for focus; this is done during headlight manufacturing.
Because the composite headlight asse mbly is bolted into position, no
adjustment should be necessary or possibl e. Some applications, however, may
be bolted to an adjuster plate or may be retained by adjusting screws. If so,
follow this procedure when adjusti ng the lights, BUT always have the
adjustment checked by a reputable shop.
Before removing the headlight bulb or di sturbing the headlamp in any way, note
the current settings in order to ease headlight adjustment upon reassembly. If
the high or low beam setting of the old la mp still works, this can be done using
the wall of a garage or a building:
1. Park the vehicle on a level su rface, with the fuel tank about
1/2 full and
with the vehicle empty of all extra cargo (unless normally carried). The
vehicle should be facing a wall whic h is no less than 6 feet (1.8m) high
and 12 feet (3.7m) wide. The front of the vehicle should be about 25 feet
from the wall.

FOG LIGHTS
REMOVAL & INSTALLATION
1. Remove the two screws attaching the lamp assembly to the front impact
bar.
2. Remove the lamp assembly from the impact bar.
3. Disconnect the electrical connector.
4. Remove the two lens attaching screws.
5. Remove the bulb.
6. Installation is the reverse of removal.

AIMING
Check with your local authorities before performing this procedure. Most areas
have standards for proper adjustment. We recommend, for safety, that the
adjustment always be checked by a reputable shop.
1. Prepare the vehicle as follows: a. Make sure all com ponents are in place.
b. Make sure the vehicle has a
1/2 tank of fuel or less.
