8-132 METERS AND GAUGES - Service Adjustment Procedures
(5) If both the test light and gauge operate, the circuit to the
gauge unit is normal and the gauge unit itself is faulty.
If the test light flashes but the gauge does not operate, the
gauge is faulty.
If 1 neither the test light nor the gauge operates, the water
temperature gauge circuit is faulty.

To check the water temperature gauge unit, first remove it
from the intake manifold.
For detailed information concerning installation of the water
temperature gauge unit, refer to GROUP 11, INTAKE AND
EXHAUST SYSTEM - Intake Manifold.
WATER TEMPERATURE GAUGE UNIT RESISTANCE CHECK
Immerse the gauge unit in hot water at 70°C (158°F) and
measure the resistance value with an ohmmeter.
Standard value: 90.5 - 117.5 LR
OIL PRESSURE GAUGE SIMPLE TEST NOEHIFA
(1) Disconnect the wiring connector from the oil pressure
gauge unit inside the engine compartment.
(2) Ground the connector at the harness through a test light.
(3) Turn the ignition key to the ON position.
(4) Check to be sure that the test light illuminates steadily and
the indicator of the oil pressure gauge moves.
(5) If both the test light and gauge operate, the circuit to the
gauge unit is normal and the gauge unit itself is faulty.
If the test light flashes but the gauge does not operate, the
gauge is faulty.
If neither the test light nor the gauge operates, the oil
pressure gauge circuit is faulty.

Measure the resistance value between t.he terminals by using
an ohmmeter.
Standard value :

l-3 terminals: 23-27 R
122-148 Sz
100-120 IR
Caution
If there is a malfunction of the ground contact of the
voltage regulator even once during vehicle operation,
the excessive current flowing through the heat coil of
the water temperature gauge and the fuel gauge will
cause permanent distortion of the bimetal, resulting in
the indications being consistently lower than the actual
value.
For this reason, therefore, be sure to make the earth
contact securely.

an ohmmeter.

2. INSTALLATION OF SPEEDOMETER CABLE
Insert the cable until its stopper properly fits to the

Caution
Poor installation of the cable may cause a fluctuating

INCLINOMETER
OUTLINE
The inclinometer is an instrument which indicates the forward
or backward inclination (pitching) or side to side inclination
(ding) of vehicle.
Motion of a pendulum in the system is displayed on the
system. The pitching and rolling pointer is supported by a
double support mechanism in which the rolling fulcrum is
supported in such a way as to be rotative around the case and
the pitching fulcrum supported on the rolling system
CONSTRUCTION
The inclinometer consists of an outer case which inclines with
the vehicle, a pointer which is provided in an oil case and
always maintains a level position, and a spherical dial. The
spherical dial is coupled through the dial support plate to the
rolling damper plate. The rolling damper plate is swivel bearing
coupled to a stationary frame by the center axis, so it can
incline side-to-side, but is always held in a level position by a
pendulum. The pointer is coupled with the pitching damper
plate.
Since the pitching damper plate is swivel bearing coupled to
the rolling damper plate by the center axis, it can incline
forward and backward, but is always maintained in a level
position by the pendulum.
OPERATION
The side-to-side inclination angle should be read on a scale of
the front panel as indicated by the horizontal centerline of the
spherical dial, whereas the forward or backward inclination
angle should be read on a scale of the spherical dial as
indicated by the pointer.
