(b) Submerge the switch in fuel, and check that the bulb goes
out.
If operation is not as specified, replace the sender gauge.
7. INSPECT RECEIVER ENGINE COOLANT
TEMPERATURE GAUGE OPERATION
(a) Disconnect the connector from the sender gauge.
(b) Turn the ignition switch ON, and check that the receiver
gauge needle indicates COOL.
(c) Ground terminal on the wire harness side connecter
through a 3.4 W test bulb.
(d) Turn the ignition switch ON, check that the bulb lights up
and the receiver gauge needle moves to the hot side.
If operation is as specified, replace the sender gauge. Then, re-
check the system.
If operation is not as specified, measure the receiver gauge re-
sistance.
8. INSPECT ENGINE COOLANT TEMPERATURE
RECEIVER GAUGE RESISTANCE
Measure the resistance between terminals.
w/ Tachometer:
Between terminalsResistance (W)
D - EApprox. 51.0
D - FApprox. 148.6
E - FApprox. 199.6
w/o Tachometer:
Between terminalsResistance (W)
A - BApprox. 54.0
A - CApprox. 175.7
B - CApprox. 229.7
HINT:
Connect the test leads so that the current from the ohmmeter
can flow according to the above order. This circuit includes the
diode.

If resistance value is not as specified, replace the receiver
gauge.
9. INSPECT LOW OIL PRESSURE WARNING LIGHT
(a) Disconnect the connector from the warning switch and
ground terminal on the wire harness side connector.
(b) Turn the ignition switch ON, and check that the warning
light lights up.
If the warning light does not light up, test the bulb.
10. INSPECT LOW OIL PRESSURE SWITCH CONTINUITY
(a) Disconnect the connector from the switch.
(b) Check that there is continuity between terminal and
ground with the engine stopped.
(c) Check that there is no continuity between terminal and
ground with the engine running.
HINT:
Oil pressure should be over 49 kPa (0.5 kgf/cm
2, 7.1 psi).
If operation is not as specified, replace the switch.
11. INSPECT BRAKE SYSTEM WARNING LIGHT
(a) Disconnect the connectors from the level warning switch
and parking brake switch.
(b) Connect terminals on the wire harness side connector of
the level warning switch connector.
(c) Turn the ignition switch ON, and check that the warning
light lights up.
If the warning light does not light up, test the bulb.
12. INSPECT BRAKE FLUID LEVEL WARNING SWITCH
CONTINUITY
(a) Check that there is no continuity between terminals with
the switch OFF (float up).
(b) Check that there is continuity between terminals with the
switch ON (float down).
If operation is not as specified, replace the switch.
