General information
The electrical system is a 12-volt, nega-
tive ground type. Power for the lights and all
electrical accessories is supplied by a
lead/acid-type battery which is charged by
the alternator.
This Chapter covers repair and service
procedures for the various electrical compo-
nents not associated with the engine. Infor-
mation on the battery, alternator, distributor
and starter motor can be found in Chapter 5.
Warning: When working on the electrical sys-
tem, disconnect the negative battery cable
from the ground stud on the left shock tower
(see Chapter 5, Section 1) to prevent electri-
cal shorts and/or fires.
2
Electrical troubleshooting
A typical electrical circuit consists of an
electrical component, any switches, relays,
motors, fuses, fusible links or circuit breakers
related to the component and the wiring and
connectors that link the component to both
the battery and the chassis. To help pinpoint
an electrical circuit problem, wiring diagrams
are included at the end of this Chapter.
Before tackling any troublesome electri-
cal circuit, first study the appropriate wiring
diagrams to get a complete understanding of
what makes up that individual circuit. Trouble
spots, for instance, can often be narrowed
down by noting if other components related
to the circuit are operating properly. If several
components or circuits fail at one time,
chances are the problem is in
a
fuse or
ground connection, because several circuits
are often routed through the same fuse and
ground connections.
Electrical problems usually stem from
simple causes, such as loose or corroded
connections, a blown fuse, a melted fusible
link or a bad relay. Visually inspect the condi-
tion of all fuses, wires and connections in a
problem circuit before troubleshooting it.
If testing instruments are going to be utilized,
plan ahead of time where to make the neces-
sary connections to accurately pinpoint the
trouble spot.
The basic tools needed for electrical
troubleshooting include a circuit tester or
voltmeter (a 12-volt bulb with a set of test
12
12-2
Chapter 12 Chassis electrical system
leads can also be used), a continuity tester
(which includes a bulb, battery and set of test
leads) and a jumper wire, preferably with a
fuse or circuit breaker incorporated, which
can be used to bypass electrical components.
Before attempting to locate a problem with
test instruments, use the wiring diagram(s) to
decide where to make the connections.
Voltage checks
Voltage checks should be performed if a
circuit isn't functioning properly. Connect one
lead of a circuit tester to either the negative
battery terminal or a known good ground.
Connect the other lead to a connector in the
circuit being tested, preferably nearest to the
battery or fuse. If the bulb of the tester lights,
voltage is present, which means the part of
the circuit between the connector and the
battery is problem free. Continue checking
the rest of the circuit in the same fashion.
When you reach a point where no voltage is
present, the problem lies between that point
and the last test point with voltage. Most of
the time the problem can be traced to a loose
connection. Note:
Keep
in mind that
some
circuits
receive voltage
only when the ignition
key is in the Accessory
or
Run position.
Finding a short
One method of finding a short in a cir-
cuit is to remove the fuse and connect a test
light or voltmeter in its place to the fuse ter-
minals. There should be no voltage present
in
the circuit. Move the wiring harness from
side-to-side while watching the test light. If
the bulb lights, there's a short to ground
somewhere in that area, probably where the
insulation has rubbed through. The same test
can be performed on each component in the
circuit, even a switch.
"Short finders" are also commonly avail-
able. These reasonably priced tools connect
in place of a fuse and pulse voltage through
the circuit. An inductive meter (included with
the kit) is then run along the wiring for the cir-
cuit. When the needle on the meter stops
moving, you've located the short.
Ground check
Perform a ground test to check whether
a component is properly grounded. Discon-
nect the negative battery cable from the
ground stud on the left shock tower and con-
nect one lead of a self-powered test light,
known as a continuity tester, to a known
good ground. Connect the other lead to the
wire or ground connection being tested. If the
bulb lights, the ground is good. If the bulb
doesn't light, the ground is faulty.
Continuity check
A continuity check is done to determine
if there are breaks in a circuit - if it's capable
of passing electricity properly. With the circuit
off (no power in the circuit), a self-powered
continuity tester can be used to check it.
Connect the test leads to both ends of the
circuit (or to the "power" end and a good
ground) - if the test light comes on the circuit
is passing current properly. If the light does-
n't come on, there's a break (open) some-
where in the circuit. The same procedure can
be used to test a switch by connecting the
continuity tester to the switch terminals. With
the switch on, the test light should come on.
Finding an open circuit
When diagnosing for possible open cir-
cuits, it's often difficult to locate them by
sight because oxidation or terminal misalign-
ment are hidden by the connectors. Merely
wiggling a connector on a sensor or in the
wiring harness may correct the open circuit
condition. Remember this when an open is
indicated when troubleshooting a circuit.
Intermittent problems may also be caused by
oxidized or loose connections. Electrical
troubleshooting is simple if you keep in mind
that all electrical circuits are basically elec-
tricity running from the battery, through the
wires, switches, relays, fuses and fusible
li nks to each electrical component (light bulb,
motor, etc.) and to ground, where it's passed
back to the battery. Any electrical problem is
an interruption in the flow of electricity to and
from the battery.
3
Fuses - general information
Refer
to illustrations 3. la, 3. lb and 3.3
1
The electrical circuits of the vehicle are
protected by a combination of fuses, circuit
breakers and fusible links. One fuse block is
located under a cover on the end of the
instrument panel on the left (driver's) side,
easily accessible by opening the driver's door
(see illustration). A fuse and relay block,
called the Power Distribution Center (PDC) is
located on the left side of the engine com-
partment near the radiator upper support
(see illustration).
2
Each fuse, relay or circuit breaker is
designed to protect a specific circuit. The
various circuits and fuses are identified on
the underside of the PDC or fuse block cov-
ers.
3
Miniaturized fuses are employed in the
fuse block. These compact fuses, with blade
terminal design, allow fingertip removal and
replacement. If an electrical component fails,
always check the fuse first. A blown fuse is
3.1a The interior fuse block is located at
the left end of the instrument panel - open
the driver's door and pull off the cover.
Fuse identification is located on the
underside of the cover
3.1b The Power Distribution Center is located in the engine
compartment and contains both fuses and relays (additional
relays are under the square cover directly above the PDC)
3.3 The fuses used on these models can be checked visually to
determine if they are blown (good fuse on right,
blown fuse on left)
Chapter 12 Chassis electrical system

4.2 Strip about 1 inch of insulation off both wires, then spread the
strands, push them together and twist them in place
7.1 The turn signal/hazard flasher unit is located in the steering
column and mounted behind multi-function switch
easily identified through the clear plastic
body. Visually inspect the element for
evi-
dence of damage (see illustration). If a con-
tinuity check is called for, the blade terminal
tips are exposed in the fuse body.
4
Be sure to replace blown fuses with the
correct type and rating. Fuses of different rat-
ings are physically interchangeable, but only
fuses of the proper rating should be used.
Replacing a fuse with one of a higher or lower
value than specified is not recommended.
Each electrical circuit needs a specific
amount of protection. The amperage value of
each fuse is molded into the fuse body.
5
If the replacement fuse immediately
fails, don't replace it again until the cause of
the problem is isolated and corrected. In
most cases, the cause will be a short circuit
in the wiring caused by a broken or deterio-
rated wire.
4
Fusible links - general
information
Refer to illustration 4.2
1
The circuit from the output terminal of
the Power Distribution Center to the alterna-
tor and the starter motor (1995 and 1996
vehicles with manual transaxles only) is pro-
tected by a wire called a fusible link. Fusible
li nks are used in circuits which are not ordi-
narily fused, such as the starting or ignition
circuit(s).
2
Although the fusible links appear to be a
heavier gauge than the wires they're protect-
ing, the appearance is due to the thick insula-
tion. All fusible links are four wire gauges
smaller than the wire they're designed to pro-
tect. Fusible links cannot be repaired, but a
new link of the same amperage rating can be
installed. The procedure is as follows:
a) Disconnect the negative cable from the
remote battery terminal.
b) Disconnect the fusible link from the
component at the eyelet terminal con-
nection.
c) Cut the damaged fusible link out of the
wiring just behind the crimp connector.
d) Strip the insulation back approximately
1-inch.
e) Spread the strands of the exposed wire
apart, push them together and twist
them in place (see illustration). Note: If
available, this connection may be made
using another crimp type connector.
Use rosin core type solder and solder
the wires together to obtain a good con-
nection.
Use plenty of electrical tape around the
soldered joint. No wires should be
exposed.
h) Connect the new fusible link eyelet ter-
minal to the component and tighten the
screw securely.
i) Connect the negative cable to the
remote battery terminal. Test the circuit
for proper operation.
5
Circuit breakers - general
information
Circuit breakers protect components
such as power windows, power door locks,
power seats and sunroof (if equipped). The
circuit breakers are located in the fuse block.
On some models the circuit breaker resets
itself automatically, so an electrical overload
in the circuit will cause it to fail momentarily,
then come back on. If the circuit doesn't
come back on, check the circuit breaker
immediately (some circuit breakers must be
reset manually). If the circuit breaker blows
again, check the circuit for a short and cor-
rect it as soon as possible. Once the condi-
tion is corrected, the circuit breaker should
resume its normal function.
6
Relays - general information
Several electrical circuits in the vehicle
that draw heavy amperage utilize relays to
transmit current to the component. If the
relay is defective, the component won't oper-
ate properly. Relays are located in the fuse
block and the Power Distribution Center (see
illustrations 3.1a and 3.1b).
If a faulty relay is suspected, it can be
removed and tested by a dealer service
department or other qualified repair shop.
Defective relays are not serviceable and must
be replaced as a unit. Note: Checks for the
starter, automatic shutdown and fuel pump
relays are located in Chapter 4.

Turn signal/hazard flasher -
check, removal and installation
Warning: These models have airbags. Always
disable the airbag system before working in
the vicinity of the impact sensor, steering col-
umn or instrument panel to avoid the possibil-
ity of accidental deployment of the airbag,
which could cause personal injury (see Sec-
tion 29).

2
When the flasher unit is functioning
properly, an audible click can be heard during
its operation. An inoperative or incomplete
turn signal circuit will result in an increased
flasher speed.

If both turn signals fail to blink, the prob-
lem may be due to a blown fuse, a faulty
flasher unit, a broken switch or a loose or

should be indicated. Connect the voltmeter
to terminal no. 2 (-) and 3 (+), place the wiper
switch in the LO position - voltage should be
indicated. If no voltage is indicated in either
position, check for continuity between termi-
nal no. 2 and ground, if no continuity is indi-
cated, repair the ground connection.
4
If voltage is present in the HI and LO
positions, remove the motor and check it off
the vehicle with fused jumper wires con-
nected to the battery remote terminals. If the
motor now operates, check for binding link-
age. If the motor still does not operate,
replace it.

14.3 While protecting the body paint with padding
placed between the screwdriver and the fender, use a
screwdriver to carefully pry the headlight assembly from
the ball socket (arrow)
li ght assembly, carefully pry the headlight
assembly away from the fender to disengage
it from the ball socket (see illustration).

Disconnect the electrical connectors
from the headlight and park/turn signal bulb
holders and remove the headlight assembly
from the vehicle.

Installation is the reverse of removal.
Make sure the electrical connectors are
securely attached. Adjust the headlights if
necessary (see Section 15).

Headlight and fog light -
adjustment
Warning: The headlights must be aimed cor-
rectly. If adjusted incorrectly, they could tem-
porarily blind the driver on an oncoming vehi-
cle and cause an accident or seriously reduce
your ability to see the road. The headlights
should be checked for proper aim every 12
months and any time a new headlight is
installed or front end body work is performed.
The following procedure is only an interim
step to provide temporary adjustment until
the headlights can be adjusted by a dealer
service
department
or other properly
equipped shop.
Headlights
Using the built-in indicators
Refer to illustrations 15.4 and 15.6
1
The headlight assemblies have built-in
horizontal and vertical position indicators
which are calibrated at the factory.
2
Adjustment should be made with the
vehicle on a level surface, with a full gas tank
and a normal load in the vehicle.
3
Rock the vehicle side-to-side three
ti mes, then push down on the front bumper
to jounce the front suspension up-and-down
three times. This will allow the suspension to
stabilize prior to adjustment.
4
Open the hood and check the vertical
indicators on the headlight assemblies. The
bubble in the vial should be centered over the
zero (see illustration). Note: A bubble
located anywhere between 0.75 degrees UP
and 0.75 degrees DOWN is also acceptable.
5
If the bubble is not within the 0.75
degrees UP to 0.75 degrees DOWN range,
adjust the vertical aiming screw (see illustra-
tion 15.1) as required to bring the bubble
back to the centered location. Caution: Do
not tamper with the screw on the vial itself or
calibration will be lost.
6
Next, check the horizontal indicators.
The arrow on the adjuster should be pointing
to the zero mark on the gauge wheel (see
illustration).
7
If the arrow is not pointing to the zero
mark, adjust the horizontal aiming screw (see
illustration 15.6) as required to align the hor-
izontal marks.
Using an alignment screen
Refer to illustration 15.13
8
This procedure requires a level surface
and a flat blank wall with room to park the
vehicle 25 feet from the wall.
9
Position a masking tape line vertically on
the wall in reference to the centerline of the
vehicle and the headlights. Note: It may be
easier to position the tape on the wall with the
vehicle parked only a few inches away, then
move the vehicle directly backwards away
from the wall.
10
With the vehicle 25 feet away from the
wall, rock the vehicle side-to-side three times,
then push down on the front bumper to
jounce the front suspension up-and-down
three times. This will allow the suspension to
stabilize.
15.6 Headlight horizontal position
indicator - When properly adjusted, the
arrow on the adjuster should be pointing
to the zero mark on the gauge wheel
11
Measure the distance from the floor to
the centerline of each headlight lens. Transfer
these dimensions to the wall and place
another masking tape line horizontally at
each location.
12
Measure the distance from the center-
li ne of each headlight lens to the center of the
vehicle. Transfer these dimensions to the flat
wall on each side of the vertical centerline
tape line and place a masking tape line verti-
cally at each location.
13
On the wall at the left headlight location,
place a 2 inch square piece of tape 8 inches
below the horizontal line and 5 inches to the
right of the vertical centerline. This is the target
spot for the left headlight (see illustration).
