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 onehal
f
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.

POWER STEERING SYSTEM

4. OVERVIEW
The power steering system consists of pump, oil reservoir, rack and pinion gear. The power
steering pump is a vane type and delivers hydraulic pressure to operate the power steering
system. The pressure relief valve in pump controls the discharging pressure.
The rotary valve in rack and pinion gear directs the oil from the power steering pump to one
side of rack piston.
The integrated rack piston converts the hydraulic pressure to linear movement.
The operating force of rack moves the wheels through tie rod, tie rod end and 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 steering wheel is conveyed to pinion, and the movement o
f
pinion moves the rack through pinion gear combined to rack gear.

POWER STEERING SYSTEM
3. POWER STEERING PUMP
The vane type pump that is connected to engine by belt is used for the power steering system.
This pump generates and controls a proper hydraulic pressure and flows by using the flow
control valve and pressure relief valve.
The flow control valve regulates the excessive amount of discharging oil. When the steering
wheel is stationary or the oil circuit is blocked, the pressure relief valve returns the ove
r
pressurized oil to the oil reservoir.
4. OIL RESERVOIR
The oil reservoir sends the oil to the power steering pump and receives the oil from the power
steering gear.
The oil level in the reservoir depends on the steering wheel positions. therefore, measure the oil
level when the steering wheel is positioned at straight ahead direction (neutral).

5) Air Mix Door Actuator
The air mix door actuator controls the discharging air temperature properly by closing/opening
the damper according to the control signals from FATC.
