0 Try the following checks before doing the
System Diagnosis.
1. Check that the Headlights and Park Lights
work properly before troubleshooting the Fog
Lights.
2. If one Fog Light doesn't work, check the Fog
Light, connections, and wires to the Fog
Light.
3. If the Fog Light Switch is not illu
when the Park Lights are on, check the
GRU
(8) wire.
4.
If the FOG LIGHTS ON Light and the
Panel Light do not operate, check the BLK
(150) wire for an open.
Go to System Diagnosis for diagnostic tests.

GENERAL BESCRIP"T0N
RALLY GAGES
Figure I
The Rally Gage option, available on most models,
consists of an engine water temperature gage, an oil
pressure gage and a voltmeter.
These gages are incorporated into the instrument
cluster and replace the standard warning lamps. The
water temperature and oil pressure gages are
electrically operated from sending units mounted in the
cylinder head and oil filter base respectively. The
voltmeter registers regulated voltage, providing an
indication of the charging system's ability to keep the
battery charged. Continuous readings in either the high
or low voltage red bands can indicate improper voltage
regulation, broken or slipping alternator belt,
a shorted
alternator diode
or a defective battery. Readings in the
yellow band are normal with the engine idling or for
short periods after long engine cranking. However,
continuous readings in the yellow band can indicate
faulty operation. See Section
8A for diagnosis.
TACHOMETER
Figure 2
The tachometer indicates speed of the engine in
revolutions per minute (RPM). The engine can safely
be operated up to a maximum RPM as indicated by the
start of the red bar. Engine operation with tachometer
readings in the red area can lead to serious engine
damage.
Due to its dual-coil design, the tachometer may
not return to zero when the ignition
is turned oft: This
is
a normal condition and should not be diagnosed as
a problem in the tachometer.
TRIP ODOMETER
The trip odometer can be reset by twice fully
depressing the push button located on the right side of
the speedometer cluster. The first depression shows all
zeroes, and the second locks them in position. Both
depressions must be done to avoid possible half cycling

of the trip odometer. A slow, steady push should be
used to avoid damage to the internal mechanism.
Do not reset the odometer with the
vehicle in motion. Damage to the odometer
may occur.
The trip odometer does not affect service
procedures for speedometers listed in Section
8C.

surface of the rear glass. Current is applied to this grid
through a control switch on the instrument panel to
warm and defog the glass. A defogger timer, which is
also activated when the switch is depressed, allows
current flow through the rear window grid
for
approximately 10 minutes on first application
(approximately
5 minutes on subsequent applications)
and automatically shuts off the system. The system can
be turned off at any time by pushing the control switch
to the "OFF" position. The system is designed to
operate only when the ignition is on and must be
reactivated whenever the ignition has been turned off
and turned on again. Care should be exercised when
cleaning the inside rear glass so as not to scratch or
remove any of the grid material. Damage to the grid
could cause an open circuit. A monitor lamp in-the
control switch indicates power being fed to the rear
window grids so the operator can determine when the
system is operating.
The electric rear window defogger system
incorporates an electrical grid fused to the inside

Electric powered remote control mirrors are
available with a control that allows the mirrors to be

RALLY GAGES ELECTRIC REAR WINDOW DEFOGGER
Diagnosis of individual rally gages is found in
Section
8A Figure 4
TACHOMETER To check for moper o~eration of the rear window
1. Insure that the in-line or fuseblock fuse is not
blown. (See Section 8A for wiring information.)
2. With ignition off, remove the tachometer from
the cluster to gain access to the connectors. Turn
ignition on and check for
12 volts at the power
input connector
(pink/black) and no voltage at
ground (black). Connect a test light to the brown
wire which connects to the "TACH" terminal of
the distributor. With the engine idling, a test light
should light with approximately the same
intensity as when attached to
12 volts. As the
engine speed increases, the test light intensity
should decrease.
3. If proper signals are present at the connector,
replace the gage. If not, the problem is in the
wiring to the gage.
Some tachometers use a circuit shorting bar
to accommodate usage on several engine
models. If tachometer readings are
significantly wrong (for example, tach reads
2900 RPM with engine at 2000 RPM),
check for a shorting bar on the back of the
tach and insure proper position (Figure
3).
If position is correct, tach must be repaired.
(Not all tachometers use a shorting bar).
Due to its dual-coil design, the tachometer
may
- grid, start the engine a& actuate the system by
depressing the control switch to the
"ON" position.
Contact one probe of a test lamp to one of the left side
rear window garnish molding screws. With the other
test lamp probe tip removed (so as not to damage the
grid), contact the bare wire to the grid adjacent to the
garnish molding. The test lamp should glow at full
brilliance. Contact the same grid line midway across
the window. The lamp should glow at half brilliance.
Repeat the procedure for each grid line. If an open
circuit exists in a grid line between the left side and the
center, the test lamp will not glow. If there is an open
circuit between the center and the right side, the test
lamp will glow more brilliantly at the center than if the
line were unbroken.
Rear window grid repairs may be made by
following the procedure published in
Section 2H of the
Body Service Manual.
The electric defogger system, wiring and
troubleshooting, is covered in Section
8A, "Electrical
Diagnosis". A quick-check troubleshooting guide is
