(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 -

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 incorporates 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 one half
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.

1. OVERVIEW
The power steering has been designed to make the wheel move more easily than in a manual steering
system. The hydraulic power assists the process utilizing hydraulic fluid. The fluid increases pressure
in the power steering pump and aids the movement of the steering mechanism. The power steering
system consists of pump, oil reservoir, rack and gear box. The power steering pump is a vane type
and delivers hydraulic pressure to operate the power steering system. The pressure relief valve in the
pump controls the discharging pressure. The rotary valve in the rack and the pinion gear directs the oil
from the power steering pump to one side of the rack piston. The integrated rack piston converts the
hydraulic pressure to linear movement. The operating force of the rack moves the wheels through the
tie rod, the tie rod end and the steering knuckle. Even though the hydraulic pressure cannot be
generated, a driver can steer the vehicle without power assist but it needs very high steering force. In
this case, the operating force of the steering wheel is conveyed to the pinion, and the movement of the
pinion moves the rack through the pinion gear combined to the rack gear.
