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.

VVATER TEMPERATURE GAUGE UNIT ONSPEC-
TION
NOBHIKD
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.

FUEL GAUGE
Measure the resistance value between t.he terminals by using
an ohmmeter.
Standard value :
l-2 terminals:
2-3 terminals:
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.
WATER TEMPERATURE GAUGE
Measure the resistance value between the terminals by using
an ohmmeter.
Standard value:
Bimetal type
l-2 terminals: 50-80 n
SERVICE POINTS OF INSTALLATION
2. INSTALLATION OF SPEEDOMETER CABLE
Insert the cable until its stopper properly fits to the
speedometer groove.
Caution
Poor installation of the cable may cause a fluctuating
meter pointer, or noise and a damaged harness inside
the instrument panel.
