II. Charging system inspection1. Check battery working voltage
(1) After having driven the vehicle and in the case that 20 minutes
have not passed after having stopped the engine,turn the ignition
switch ON and turn on the electrical system (headlight,blower
motor) for 60 seconds to remove the surface charge.
(2) Turn the ignition switch OFF and turn off the electrical
systems. Then measure the battery voltage between the nega
tive and positive terminals of the battery.
Standard voltage: 12.5-12.9V at 20°C
Hint:
If the voltage is less than specification, charge the battery.
2. Check battery terminals, fuse box and fuse
(1) Check that the battery terminals are not loose or corroded.
(2) Check if fuse box and fuse for continuity.
3. Inspect drive belt
(1) Check the belt for excessive wear, frayed cords etc.
Hint:
If any defect has been found, replace the drive belt.
Cracks on the rib side of a belt are considered acceptable. If the
belt has chunks missing from the ribs, it should be replaced.
(2) Check that the belt fits properly in the ribbed grooves.
Hint:
Check with your hand to confirm that the belt has not slipped out
of the groove on the pulley.
4. Check alternator wiring
Check that the wiring is in good condition.Automobile Starting, Power Supply System -Charging system5-45. Listen for abnormal noises from alternator
Check that there is no abnormal noise from the alternator while the engine is running.
6. Inspect charge warning light circuit
Turn the ignition ON. Check that the charge warning light comes on. Start the engine. Check that the light
goes off.
Hint:
If the light does not work as normal, troubleshoot the charge warning light circuit.
Automobile Starting, Power Supply System -Charging system5-57. Inspect charging circuit without load
(1) If a battery/starter tester is available, connect the tester to the
charging circuit as per instructions.
(2) If a tester is not available, connect an ammeter and voltmeter
to the charging circuit as follows.
a. Disconnect to the wire from terminal B of the alternator
and connect it to the negative (-) pole of the ammeter.
b. Connect the positive (+) pole of the ammeter to terminal B
of the alternator.
c. Connect the positive (+) pole of the voltmeter to terminal B
of the alternator.
d. Ground the negative (-) pole of the voltmeter.
(3) Check the charging circuit
With the engine running from idle to 2,000 rpm, check the reading on the ammeter.
Standard amperage: 10A or less
Standard voltage: 12.9V-14.9V
8. Inspect charging circuit with load
(1) With the engine running at 2,000 rpm, turn on the high beam headlights and place the blower switch at "4".
Check the reading on the ammeter.
Standard amperage: 20A or more
(2) Hint:
If the ammeter reading is less than standard amperage, repair the alternator.
If the battery is fully charged, the indication value will sometimes be less than standard amperage.III. Alternator inspection1. Inspection of alternatorPullyStatorBearingBearing spacerRotorBearing cover

Chapter 4 Light SystemSection 1 Light System IntroductionI. Composition Light system comprises external illumination and signal system and internal illumination system.
The function of the external illumination and signal system is to illuminate the road ahead and send signals
to other vehicles.
The internal illumination system provides internal illumination for driver and passengers.II. Precaution for service1. Precaution when repairing electrical equipments
Disconnect the battery ground cable.
2. Precaution when replacing a headlamp bulb
(1) Before replacing a halogen bulb, turn the headlamp OFF to make it cool.
(2) When installing a new halogen bulb, do not touch the glass part of the bulb with bare hands.
(3) If there is oil stain on the surface of halogen bulb (headlamp and front fog lamp) when the lamps are
turned ON, its service life will be shortened.
(4) Halogen bulbs (headlamp and front fog lamp) have pressurized gas inside and require special handling.
They can explode if dropped to ground. The glass fragments will splash up.
(5) When replacing, make sure to use the bulbs with the same power, same model.
(6) After the bulb is installed, make the lamp holder tight.III. Bulb specificationsRemark: All bulbs are made by Philips Corp..Light System-
