POWER SUPPLY ROUTING
This diagram is helpful in identifying specific prob-
lems
in the power supply portion of the electrical
circuits. For example, let's say
a vehicle has an in-
operative
rear window defogger A quick check
proves that meter and
gauges in the vehicle are
operative The power supply diagram shows that
there cannot be
a problem between the battery,
ignition relay, ignition switch or fuse since the
power supply circuit for the
rear window defogger
Example

ABBREVIATIONS
is common with the meter and gauges. Therefore,
the cause of this specific problem must
lie past the
fuse, such
as in the wiring, rear window defogger,
or ground.
WIRING DIAGRAM
This diagram identifies types and number of con-
nectors, electrical
terminal positions in the connec-
tor, color coding of wires, and connector codes
Refer to the following example

Fuse Fusible Link

c d
If fuse is blown, be sure to eliminate cause of
problem before installing new fuse
Use fuse of specified rating. Never use fuse of
more than specified rating
Do not install fuse in oblique direction, always
insert
it into fuse holder properly
Remove fuse for clock if vehicle
is not used for
a long period of time.
A melted fusible link can be detected either by
visual inspection or by feeling with finger tip If its
condition is questionable, use circuit tester or test
lamp
CAUTION
a If fusible link should melt, it is possible that
critical circuit (power supply or large current
carrying circuit)
is shorted In such a case, care-
fully check and eliminate cause
of problem
Never wrap periphery
of fusible link with vinyl
tape Extreme care should
be taken with this
link to ensure
that it does not come into con-
tact with any other wiring harness or vinyl or
rubber parts

Installation
1 Set the headlamp motor to "DOWN" position
Connect harness
to headlamp motor and set
retract switch to "DOWN" Headlamp motor
can now be
set to "DOWN" with retract
switch Install the headlamp link assembly and head-
lamp motor in the body
When installing the link to the motor, make
sure the motor link is installed as shown below

Adjustment
After installing connecting link, always adjust
it as follows
1) Set the headlamp to "DOWN" positlon
2) Adjust connecting link so that the lid IS proper-
ly aligned with hood and fender
3) Set the headlamp to "UP" position
