HINT:
wºNew beltº refer to a belt which has been used 5 minutes
or less on a running engine.
wºUsed beltº refers to a belt which has been used on a running
engine for 5 minutes or more.
wAfter installing a belt, check that it fits properly in the
ribbed grooves.
wCheck by hand to confirm that the belt has not slipped out
of the groove on the bottom of the pulley.
wAfter installing a new belt, run the engine for about 5
minutes and recheck the belt tension.
4. VISUALLY CHECK ALTERNATOR WIRING AND
LISTEN FOR ABNORMAL NOISES
(a) Check that the wiring is in good condition.
(b) Check that there is no abnormal noise from the
alternator white the engine is running.
6. INSPECT CHARGING CIRCUIT WITHOUT LOAD
HINT: If a battery/alternator tester is available, connect the
tester to the charging circuit as per manufacturer's instruc-
tions.
(a) If a tester is not available, connect a voltmeter and ammeter
to the charging circuit as follows:
wDisconnect the wire from terminal B of the alternator and
connect it to the negative H probe of the ammeter.
wConnect the positive (+) probe of the ammeter to terminals
B of the alternator.
wConnect the positive (+) probe of the voltmeter to terminal
B of the alternator.
wGround the negative (±) probe of the voltmeter. 5. INSPECT CHARGE WARNING LIGHT CIRCUIT
(a) Warm up the engine and then turn it off.
(b) Turn off all accessories.
(c) Turn the ignition switch to ºONº. Check that the charge
warning light is lit.
(d) Start the engine. Check that the light goes out.
If the light does not go off as specified, troubleshoot the
charge light circuit.
± CHARGING SYSTEMOn±Vehicle InspectionCH±4

(b) Check the charging circuit as follows: .
With the engine running from idling to 2,000 rpm,
check the reading on the ammeter and voltmeter.
Standard amperage: 10 A or less
Standard voltage: 13.9 ± 15.1 V at 25
°C (77°F)
13.5 ± 14.3 V at 115°C (2390F)
If the voltmeter reading is greater than standard volt-
age, replace the IC regulator.
7. INSPECT CHARGING CIRCUIT WITH LOAD
(a) With the engine running at 2,000 rpm, turn on the high beam
headlights and place the heater blower switch at ºHlº.
(b) Check the reading on the ammeter.
Standard amperage: 30 A or more
If the ammeter reading is less than standard amperage,
repair the alternator. (See page CH±6)
HINT: With the battery fully charged, the indication will
sometimes be less than standard amperage. If the voltmeter reading is less than standard voltage,
check the IC regulator and alternator as follows:
wWith terminal F grounded, start the engine and check
the voltmeter reading of terminal B.
wIf the voltmeter reading is greater than standard voltage,
replace the IC regulator.
.. If the voltmeter reading is less than standard voltage,
check the alternator.

1. INSPECT RELAY CONTINUITY
(a) Using an ohmmeter, check that there is continuity between
terminals 1 and 3.
(b) Check that there is continuity between terminals 2 and
4.
(c) Check that there is no continuity between terminals 4
and 5.
If continuity is not as specified, replace the relay.
2. INSPECT RELAY OPERATION
(a) Apply battery voltage across terminals 1 and 3.
(b) Using an ohmmeter, check that there is continuity between
terminals 4 and 5.
(e) Check that there is no continuity between terminals 2
and 4.
If operation is not as specified, replace the relay.

CHECK AND ADJUSTMENT OF
CLUTCH PEDAL
1. CHECK THAT PEDAL HEIGHT IS CORRECT
Pedal height from asphalt shaft 181 ± 191 mm
(7:13 ± 7.52 in.)
2. IF NECESSARY, ADJUST PEDAL HEIGHT
(a) Remove the instrument lower finish panel and discon-
nect the air duct.
(b) Loosen the lock nut and turn the stopper bolt (w/o
Cruise control system) or clutch switch (w/ Cruise
control system) until the height is correct. Tighten the
lock nut.
HINT: Before rotating the clutch switch for pedal height
adjustment, disconnect the clutch switch connector.
3. CHECK THAT PEDAL FREEPLAY AND PUSH ROD
PLAY ARE CORRECT
(Pedal Freeplay)
Push in the pedal until the beginning of clutch resistance
is felt.
Pedal freeplay: 5 ± 15 mm (0.20 ± 0.59 in.)
Push rod play at pedal top: 1.0 ± 5.0 mm
(0.039 ± 0.197 in.)
4. IF NECESSARY, ADJUST PEDAL FREEPLAY AND
PUSH ROD PLAY
(a) Loosen the lock nut and turn the push rod until the free-
play and push rod play are correct.
(b) Tighten the lock nut.
(e) After adjusting the pedal freeplay, check the pedal
height.
(d) Connect the air duct and install the lower finish panel.
5. INSPECT CLUTCH RELEASE POINT
(a) Pull the parking brake lever and install wheel stopper.
(b) Start the engine and idle the engine.
(e) Without depressing the clutch pedal, slowly shift the
shift lever into reverse position until the gears contact.
(d) Gradually depress the clutch pedal and measure the
stroke distance from the point the gear noise stops
(release point) up to the full stroke end position.
Standard distance: 25 mm (0.98 in.) or more
(From pedal stroke end position to release point)
If the distance is not as specified, perform the following
operation.
wInspect pedal height.
wInspect push rod play and pedal free play.
wBleed the clutch line.
wInspect the clutch cover and disc.

BLEEDING OF CLUTCH SYSTEM
HINT: If any work is done on the clutch system or if air
is suspected in the clutch lines, bleed the system of air.
CAUTION: Do not let brake fluid remain on a painted sur-
face. Wash it off immediately.
1. FILL CLUTCH RESERVOIR WITH BRAKE FLUID
Check the reservoir frequently. Add fluid if necessary.
2. CONNECT VINYL TUBE TO BLEEDER PLUG
Insert the other of the tube in a half±filled container of
brake fluid.
3. BLEED CLUTCH LINE
(a) Slowly pump the clutch pedal several times.
(b) While depressing the pedal, loosen the bleeder plug
until the fluid starts to run out. Then close the bleeder
plug.
(e) Repeat this procedure until there are no more air
bubbles in the fluid.
