Fuel Gauge
Gauge Test
NOTE: Refer to page 23-123 for the fuel gauge system
circuit.
1. Check the No. 25 (7.5 A) fuse in the under-dash
fuse/relay box before testing.
2. Remove the rear seat (see section 20).
Remove the protective cover and access panel from
the tloor.
With the ignition switch OFF, disconnect the 3p con-nector from the fuel gauge sending unit.

Connect the voltmeter positive probe to the
YEL/WHT terminal and the negative probe to the
BLK/WHT terminal, then turn the ignition switch ON(ll). The.e should be between 5 and 8 V.
a lf the voltage is as specified, go to step 6.a lI the voltage is not as specified, check for- an open in the YEL/WHT, BLU/WHT or
BLK/WHT wire.- poor ground (G501, G502).

6.Turn the ignition switch OFF. Attach a jumper wire
between the BLKMHT and YEL/WHT terminals,
then turn the ignition switch ON {1.,.
Check that the pointer of the fuel gauge starls mov-
ing toward the "F" mark.
CAUTION: Turn the ignition switch OFF before the
pointer reaches "F" on the gauge dial, Failure to do
so may damage the tuel gauge.
NOTE: The fuel gauge is a bobbin (cross-coil) type
gauge, hence the fuel level is continuously indicat-
ed even when the ignition switch is OFF, and thepointer moves more slowlv than that ol a bimetal
rype gauge.
a lf the pointer ol the fuel gauge does not move at
all, replace the gauge.
a It the gauge is OK, inspect the fuel gauge send-
ing unit.

NOTE: Refer to page 23-123 for the wiring description of
the low fuel indicator circuit.
1. Park car on level ground.
@ oo not smoke whilc wolking on the
fuel system. Keep open tlames away from your work
area. Drain fuel only into an approved container.
2. Drain fuel into an approved container. Then install
the drain bolt with a new washer.
3. Add lessthan 8.2 t l2.2U.S.Gal, 1.8 lmp.Gal)of fuel
and turn the ignition switch ON {ll). The low fuel in-
dicator light should come on within lour minutes.
. lf the light does not come on. remove the access
panel and disconnect the 3P connector from the
fuel gauge sending unit. Connect the A (BLV
WHT) terminal to the C (BLU,/WHT) terminal with
a jumper wire.
- lf the Iight comes on, the problem is either the
sending unit or its ground.- lf the light does not come on, the problem is
an open in the BLU/WHT wire to the gauge as-
sembly, no power to the gauge, or a blown
bulb.
a lf the light comes on, add approx.4 ! (1.1
U.S.Gal. O.9 lmp.Gal) of fuel, the light should go
off within four minutes.

Headlight
Adjustment
Befole adiusting the headlights:
a Park the car on level ground.
a Make sure the fuel tank is full.
The driver or someone who weighs the same should
sit in the driver's seat.
Load the trunk with the items you usually carry (if you
usually pull a trailer, attach jt to the car).
Push down on the front and rear bumpers several
times to make sure the car is sitting normally.
When installing a new headlight assembly, tighten the
four mounting bolts so that the indicator in the verti-
cal gauge comes to the "O" mark.
HORIZONTAL ANGLEGAUGE
HORIZONTALADJUSTER
'1. Open the hood.
2. Check that both the horizontal and vertical gauge
rcad "O" .
a lf the gauges tead "O", check headlight aiming
with the aiming charts on page 23-171. (lf aiming
isn't correct. refer to the frame repair chart in
section 20).
a lf one or both gauges don't read "O", go to step
23-170
3. Turn the low beams on. lf necessary, align the verti-
cal indicator with its "O" mark by turning the verti-
cal adjuster with a Phillips screwdriver, and check
aiming with the chan on page 23-171.
lf necessary, align the horizontal indicator with its"O" mark by turning the horizontal adjuster with a
Phillips screwdriver, and check aiming with the
chart on page 23-171.
5.Recheck that the vertical indicator bubble is aligned
with "0" t 1.
lf necessary, adjust as described in step 3.
Turn the high beams on and check aiming with the
charts on page 23-171.

How To Use This Manual
The next few pages describe how this manual is organized. They also
exolain what kind of information the manual contains, what that
information means, and how to use it to troubleshoot electrical problems.
Circuit schemalics break the entire electrical system into individual
syslems, like the Low Fuel Indicator Light on the next page.
Only electrical components that work together are shown together,
so you won't be distracted by unrelated wires.
Explanations of the abbreviations and symbols used in the schematics
begin on page E. You'll need to know what they mean before you can use
a schematic effectively.

How To Use This Manual
Circuit Schematics
Each schematic reoresents one circuit.
A circuit's wires and components are
arranged to show current flow, from
power at the top of the page, to ground,
at the bottom.
Other circuits may share power or ground
terminals or wiring with the circuit shown.
A wire that connects one circuit to
another, lor example, is cut short and has
an arrowhead at the end of it pointing in
the direction of current flow. Next to the
arrowhead is the name ol the circuit or
component which shares that wiring. To
quickly check shared wiring, check the
operation of a component it serves. lf that
component works, you know the shared
wiring is OK.
All connectors are numbered (C709,
C416, etc.). Below each connector
number (except those for components)
is the number of a ohoto in the back
of the book showing the connector's
location on the car. Connector cavities
are also numbered. The numbering
sequence begins at the top left corner
of the connector as seen from eilher of
the viewpoints shown on page E.
Disregard any numbers molded into the
connector housing.
Wires are identif ied by the abbreviated
names of their colors; the second color is
the color of the stripe. Wires are also
identif ied by their location in a connector.
The number "2" next to the male and
female wire terminals at C416, for
example, means those terminals join in
cavity 2 of connector C41 6.
A complete description of schematic
symbols begins on page @.
O,e
Arowhead meanswire connects toanother ciacuit;it points in directionof current tlow.
"OK" note tellsYou how tocheck sharedwiring.
"HOT" label tells you whenthe ignition switch suppliesDower lo the fuse. \\
