(1) Checking
Using battery tester ▶
PASS (11.0 V or more): Explain to the customer that the battery is reusable.
Need to be charged (9.0 to 11.0 V): Charge the battery with a charger and reinstall it. Explain it
to the customer.
Need to be replaced (9.0 V or more): The battery should be replaced due to overdischarging. -
-
-
(2) How to use battery tester
How it works and How to use it ▶
Determine battery capacity by fixing current
(load capacity) and time and varying voltage.
Determine battery capacity based on the
amount of voltage drop when discharging a
fixed load capacity (120 A) for 5 seconds.
Connect the tester to the battery and read
the display while applying a load for 5
seconds. -

How to read display ▶
Red area (①): overdischarge or faulty
battery
Yellow area (②): Need to be charged (using
a vehicle alternator and a battery charger)
Green area (③): Normal
Red area on the left-hand side of OK (④):
Impossible to charge with an alternator
Green area with OK (⑤): Normally charged
Red area on the right-hand side of OK (⑥):
Overcharged by an alternator -

2. OPERATING PROCESS
1) Charging Flow

09-12
Alternator (115 A)
2) Charging
The alternator uses a new regulator which has three diodes. It consists of the delta stator, rectifier
bridge, slip ring and brush.
Charging time according to vehicle conditions and environment ▶
Specification: Charging a fully depleted high-
capacity battery takes twice or more as long
as charging a fully depleted battery for small
vehicles.
Temperature: The lower the temperature is,
the longer the time taken to charge the
battery. When connecting the battery charger
to the cold battery, the amount of current the
battery can accept initially is very small. As the
battery gets warmer, it can accept more
current.
Charging capacity: Charging a battery with a low-capacity charger takes longer time than
charging with a high-capacity charger.
Charging status: Charging a fully depleted battery takes twice or more as long as charging a half-
depleted battery. Since the electrolyte in a fully depleted battery consists of nearly pure water and
conductor, only a very small amount of current can be accepted by the battery initially. The
charging current increases as the amount of acids in the electrolyte is increased by the charging
current.

1. CHARGING SYSTEM OPERATION
Alternators use a new type of regulator that incorpo-rates a diode trio. A Delta stator, a rectifier
bridge, and a rotor with slip rings and brushes are electrically similar to earlier alternators.
A conventional pulley and fan are used. There is no test hole.
1) Charging Time Required
The time required to charge a battery will vary depending upon the following factors:
Size of Battery ▶
A Completely discharged large heavy-duty battery required more than twice the
recharging time as a completely discharged small passenger car battery. -
Temperature ▶
A longer time will be needed to charge any battery at -18°C (0°F) than at 27°C (80°F).
When a fast charger is connected to a cold battery, the current accepted by the battery
will be very low at first. The battery will accept a higher current rate as the battery warms. -
Charger Capacity ▶
A charger which can supply only 5 amperes will require a much longer charging period
than a charger that can supply 30 amperes or more. -
State-of-Charge ▶
A completely discharged battery requires more than twice as much charge as a onehalf
charged battery. Because the electrolyte is nearly pure water and a poor conductor in a
completely discharged battery, the current accepted by the battery is very low at first.
Later, as the charging current causes the electrolyte acid content to increase, the charging
current will likewise increase. -
2. STARTING SYSTEM OPERATION
The engine electrical system includes the battery, the ignition, the starter, the alternator, and all
the related wiring. Diagnostic tables will aid in troubleshooting system faults. When a fault is
traced to a particular component, refer to that component section of the service manual. The
starting system circuit consists of the battery, the starter motor, the ignition switch, and all the
related electrical wiring. All of these components are connected electrically.
