If circuit is as specified, try another relay.
If the circuit is not as specified, check the circuits connected to
other parts.
24. INSPECT ENGINE OIL LEVEL WARNING SWITCH
(a) Check that there is continuity between terminal with the
switch each position.
(b) Heat the switch to above 60° C (140°F) in an oil bath.
(c) Check that there is continuity between terminals with the switch ON (float up).
(d) Check that there is no continuity between terminals with
the switch OFF (float down).
If operation is not as specified, replace the switch.

25. INSPECT ENGINE OIL LEVEL WARNING CIRCUIT
Disconnect the switch connector and inspect the connector on
wire harness side, as shown.
Tester connectionConditionSpecified condition
2 − GroundConstantContinuity
If continuity is not as specified, inspect the wire harness or
ground point.
26. INSPECT ENGINE OIL LEVEL WARNING LIGHT
(a) Disconnect the connector from the switch.
(b) Ground terminal 1 on the wire harness connector.
(c) Turn the ignition switch ON, and check that the warning
light lights up approximately 40 seconds later.
If the warning light does not light up, inspect bulb or wire har-
ness.
27. INSPECT LIGHT CONTROL RHEOSTAT
(a) Connect terminals 1 and 3 through a 3.4 W test bulb.
(b) Connect the positive (+) lead from the battery to terminal
1 and the negative ( −) lead to terminal 2.
(c) Turn the rheostat knob to fully counterclockwise, and
check that the test bulb goes out.
(d) Gradually turn the rheostat knob to clockwise, and check
that the test bulb brightness changes from dark to bright.
If operation is not as specified, replace the rheostat.
HINT:
Adjust the brightness of illumination lights by rheostat.

3. INSPECT DRIVE BELTS
(a) Visually check the drive belt for cracks, oiliness or wear.
Check that the belt does not touch the bottom of the pulley
groove.
If necessary, replace the drive belts as a set.
(b) Using a belt tension gauge, measure the belt tension. Belt tension gauge:
Nippondenso BTG−20 (95506 −00020)
Borroughts No. BT−33−73F
Drive belt tension:
New belt400 − 580 N (41.0 − 59.1 kgf, 90.4 − 130.2 lbf)
Used belt200 − 390 N (20.4 − 40.0 kgf, 45.0 − 88.2 lbf)
If the belt tension is not as specified, adjust it.
HINT:
”New belt” refers to a belt which has been used less than
5 minutes on a running engine.
”Used belt” refers to a belt which has been used on a run-
ning engine for 5 minutes or more.
After installing a new belt, run the engine for about 5 min-
utes and recheck the belt tension.
4. VISUALLY CHECK GENERATOR WIRING AND LIS- TEN FOR ABNORMAL NOISES
(a) Check that the wiring is in good condition.
(b) Check that there is no abnormal noise from the generator
while the engine is running.
5. INSPECT DISCHARGE WARNING LIGHT CIRCUIT
(a) Turn the ignition switch ”ON”. Check that the discharge warning light comes on.
(b) Start the engine. Check that the light goes off.

COOLANT
INSPECTION
HINT:
Check the coolant level when the engine is cold.
1. CHECK ENGINE COOLANT LEVEL AT RADIATOR RESERVOIR
The engine coolant level should be between the ”LOW” and ”FULL”\
lines.
If low, check for leaks and add engine coolant up to the ”FULL” line.
2. CHECK ENGINE COOLANT QUALITY
(a) Remove the radiator cap.
CAUTION:
To avoid the danger of being burned, do not remove the radiator cap while the engine and radiator
are still hot, as fluid and steam can be blown out under pressure.
(b) There should not be any excessive deposits of rust or scale around the r\
adiator cap or radiator filler
hole, and the coolant should be free from oil.
If excessively dirty, replace the coolant.
(c) Reinstall the radiator cap.
