fuses.
When no battery voltage is found, the problem is between
the point where no voltage is detected, and the last place
that voltage was detected. In circuits where no voltage is
expected, the same procedure can be used except that
the DVOM is set to continuity. Place the negative (-)
probe on a wire terminal at the beginning of the circuit
and move toward the device that is not working with the
positive (+) probe. When continuity is no longer indicated,
a failed conductor or device is indicated.

1.
Check for loose or bare wires:
Check for loose wires at each terminal connection and for
worn insulation or bare wires touching the frame.
Bare
wires may cause a short circuit
.
NOTICE: If any DVOM readings indicate a faulty
wire, it is recommended that the condition of the ter-
minals and wire junction be examined. A faulty wire
must be replaced with one of the same gauge and
color, wired between the correct components, and
wire tied to the harness bundle. The faulty wire
should be cut back close to the harness and the
ends protected with vinyl electrical tape.
2.
Check battery condition:
Check for adequate battery volts (nominal 12 VDC) by
setting DVOM to 30 VDC range and place the red probe
(+) on the battery post with the green wire attached. Place
the black probe (-) on the battery post with the black wire
attached. A reading of 11 VDC or greater indicates ade-
quate battery condition. No reading indicates (a) a poor
connection between the probes and the battery terminals;
(b) a faulty DVOM. A voltage reading below 11 volts indi-
cates poor battery condition and the vehicle should be
recharged before proceeding with the test.
NOTICE: Due to the resistance of the wires involved
within the harness, voltage readings may be some-
what lower than battery voltage. A reading of 1 volt
below battery voltage is acceptable.
3.
Check power wire:
Firmly attach the black probe (-) to the battery post with
the black wire attached and the red probe (+) to the green
wire terminal at the fuse block. A reading of battery volt-
age indicates that the power wire is in good condition.
NOTICE: The power wire supplies power to the
entire fuse block.
4.
Check fuse:
Place the red probe (+) to each wire terminal on the fuse
block. A reading of battery voltage indicates that the fuse
is in good condition. No reading indicates a faulty fuse;
replace with a good 15 amp fuse.
ACCESSORY WIRING
After determining that there is power to the fuse panel,
and the fuse is good, continue checking the circuit using
the procedures previously used to check the power sup-
ply, i.e. loose or rusted connections, bare wires, continuity
of the wiring from terminal to terminal, operating condition
of switch, etc.
Use the wiring diagram (Ref. Fig. 1) to check correct wir-
ing and wire routing. If there is power at the fuse end of
the wire, there must also be power at the other end of the
wire at the switch or electrical accessory, and eventually
at the ground connection. Electricity must flow from the
fuse panel through the full length of the circuit to the
ground connection. Any interruption of electrical flow
must be corrected, whether by repairing or replacing the
wire, the switch or accessory.
LIGHT BULB REPLACEMENT
To decrease the risk of premature
bulb failure, do not allow your fin-
gers to contact new bulbs. Use
clean, dry paper or paper towels to touch the glass
part of the bulb.

Remove the front grille assembly (3), from the cowl by
removing the self threading nut (8).
NOTICE: The following procedure is applicable for
vehicles with halogen headlights.
Always handle halogen light bulbs with a clean, soft cloth.
Oil from fingers will shorten the life of a halogen bulb.
For vehicles equipped with halogen headlights mounted
in the cowl, locate bulb socket (1) on backside of light and
turn bulb socket a quarter turn counterclockwise to unlock
and pull out bulb and socket (Ref. Fig. 5).
Insert new bulb and rotate socket (1) a quarter turn clock-
wise to secure.
NOTICE: Following procedure is applicable for vehi-
cles with LED headlights.
LED headlights are designed for longevity and do not fail
often. In case of failure, however, the complete headlight
assembly must be replaced. Replacement for the single
LED headlight failed is not possible. Refer to Service
Parts Manual for the part number of the LED headlight.
To replace the LED headlight assembly (5), locate and
