6) Alternator
Alternators are equipped with internal regulators.
Unlike three-wire generators, the alternator may be used with only two connections: battery positive and
an "D+" terminal to the charge indicator lamp.
As with other charging systems, the charge indicator lamp lights when the ignition switch is turned to
RUN, and goes out when the engine is running.
If the charge idicator is on with the engine running, a charging system defect is indicated. This indicato
r
light will glow at full brilliance for several kinds of defects as well as when the system voltage is too high
or too low.
The regulator voltage setting varies with temperature and limits the system voltage by controlling roto
r
field current.
Achieve correct average field current for proper system voltage control by varying the on-off time. At high
speeds, the on-time may be 10 percent and the off-time 90 percent.
At low speeds, with high electrical loads, the on-time may be 90 percent and the off-time 10 percent.
7) Charging System
Generators 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 generators.
A conventional pulley and fan are used.
There is no test hole.
8) Starter
Wound field starter motors have pole pieces, arranged around the armature, which are energized by
wound field coils.
Enclosed shift lever cranking motors have the shift lever mechanism and the solenoid plunger enclosed
in the drive housing, protecting them from exposure to dirt, icy conditions, and splashes.
In the basic circuit, solenoid windings are energized when the switch is closed.
The resulting plunger and shift lever movement causes the pinion to engage the engine flywheel ring
gear.
The solenoid main contacts close. Cranking then takes place.
When the engine starts, pinion overrun protects the armature from excessive speed until the switch is
opened, at which time the return spring causes the pinion to disengage.
To prevent excessive overrun, the switch should be released immediately after the engine starts.

9) Starting System
The engine electrical system includes the battery, the ignition, the starter, the generator, and all the
related wiring.
Diagnostic tables will aid in troubleshooting system faults. When a fault is traced to a particula
r
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.

2) Operation Logic
▶Wiper MIST and Front Washer Coupled Wiper
The wiper relay is turned on at 0.3 seconds after from the time when the washer switch is turned
on for 0.1 to 0.59 seconds with the ignition switch "ON".If the wiper parking terminal gets off, the
wiper relay is turned off.
-
The wiper relay is turned on at 0.3 seconds after from the time when the\
washer switch is turned
on for more than 0.6 seconds with the ignition switch "ON". The wiper re\
lay gets on 3 times
immediately after turning off the washer switch.

▶Auto Washer and Wiper Switch (AFW)When the auto washer switch is turned on with the ignition switch "ON" and the INT switch
"OFF", the washer motor output gets ON for 1 second. If the system recog\
nizes the output signal,
the wiper relay output gets ON during 4 cycles and the washer motor output gets ON for 1
second. Then, the wiper relay output gets OFF after 3 cycles.

Rain sensing unit
(AUTO light integrated type)
▶INT Switch Auto Position Remi nder (Power-Up Reminder Wiper)
When turning off and on the auto INT switch, the system drives the wiper motor through LOW
relay regardless of communication with rain sensor.
When turning the INT-AUTO switch from the "OFF" to "ON" position with the ignition switch in the
"ON" mode, the LOW relay operates to drive the wiper motor for 1 cycle, regar\
dless of the rain
sensor communication.
After that, when turning the INT-AUTO switch fr om the "OFF" to "ON" position, the LOW relay
operates to drive the wiper motor for 1 cycle only if data from the rain\
sensor indicates rain drops.

Multifunction wiper switch:
AUTO and sensitivity control
A sensor that emits infrared rays through LED and
then detects the amount of rain drops by receiving
reflected rays against sensing section (rain senso
r
mounting section on the windshield) with
photodiode (auto light sensor integrated type) AUTO
: Wiper operates automatically by rain sensor
FAST↔SLOW : Auto delay/Auto speed control. A
position that can control sensitivity against rains on
the windshield and transmits wiping demand signal
accordingly

▶Washer Coupled Wiper in Rain Sensing ModeThe washer coupled wiper is operated when receiving the washer switch input with the ignition
switch and the INT-AUTO switch "ON" in the rain sensing mode. At this moment, the
communication with the rain sensor is overridden. However, a washer input is overridden if there is
an output for continuous operation.
The operation data is sent to the rain sensor even during the washer cou\
pled wiper's operation.

▶Sensitivity ControlThe wiper LOW relay is turned on and the wiper motor runs one cycle when the volume sensitivity
is increased (ex: sensitivity 0 ⇒ 1) while the ignition switch and the INT switch is in the "ON"
position, and the wiper motor is in "Parked" position). However, the wiper motor can be operated
only when the rain sensor detects the "Rain Detected" signal.
If the volume sensitivity is changed more than 2 stages within 2 seconds, the wiper motor runs
only one cycle.
