CHARGING SYSTEM
CHARGING SYSTEM
PFP:00011
System DescriptionEKS00MZA
The alternator provides DC voltage to operate the vehicle's electrical system and to keep the battery charged.
The voltage output is controlled by the IC regulator.
Power is supplied at all times to alternator terminal 4 through:
l15A fuse (No. 30, located in the fuse and fusible link box).
Terminal 1 supplies power to charge the battery and operate the vehicle's electrical system. Output voltage is
controlled by the IC regulator at terminal 4 detecting the input voltage. The charging circuit is protected by the
140A fusible link (letter "A", located in the fuse and fusible link box) .
The alternator is grounded to the engine block.
With the ignition switch in the ON or START position, power is supplied
l10A fuse [No. 14, located in the fuse block (J/B)]
lto combination meter terminal 16 for the charge warning lamp.
Ground is supplied With power and ground supplied
lto terminal 2 of the combination meter
lthrough terminal 3 of the alternator.
If the charge warning lamp illuminates with the engine running, a fault is indicated.
The charge warning lamp will illuminate. When the alternator is providing sufficient voltage with the engine
running, the ground is opened and the charge warning lamp will go off.

Check if any of the following fuses in the alternator are blown.
lCheck 15A fuse
OK or NG
OK >> GO TO 5.
NG >> If fuse is blownout, be sure to eliminate cause of malfunction befer installing new fuse.
5.CONTINUITY INSPECTION
1. Turn ignition switch OFF.
2. Disconnect combination meter connector.
3. Check continuity between combination meter connector terminal 2 and ground, and combination meter
connector terminal 2 and alternator terminal 3.
OK or NG
OK >> Replace combination meter. (Do not replace alternator, since it is normal.)
NG >> Repair the harnesses or connectors. (Do not replace alternator, since it is normal.)2 - Ground : Continuity should not exist.

2.BATTERY VOLTAGE INSPECTION
1. Turn ignition switch OFF.
2. Disconnect alternator connector.
3. Turn ignition switch ON.
4. Check voltage between alternator connector terminal 4 and
ground.
Is the inspection result 12V or more?
YES >> Replace alternator. (Alternator power generation error)
NO >> GO TO 3.
3.CHECK FUSE
Check if any of the following fuses in the alternator are blown.
lCheck 15A fuse
OK or NG
OK >> Repair the harnesses.
NG >> If fuse is blownout, be sure to eliminate cause of malfunction befer installing new fuse.
DARK CURRENT INSPECTION
Dark Current: Small current while ignition switch is “OFF”.
NOTE:
lIf battery ground cable is disconnected from battery terminal, a large dark current may not be reproduced.
When battery discharge occurs, never disconnect battery terminal while using ammeter.
lDo not connect CONSULT-II CONVERTER to data link connector when measuring dark current. CON-
SULT-II power should be supplied using AC adapter or internal battery.
1. Attach current measurement probe for CONSULT-II to battery
ground cable. Refer toSC-22, "
OPERATION PROCEDURE OF
CURRENT MEASUREMENT PROBE FOR CONSULT-II".
2. Check that all electrical equipment is turned OFF.
3. Remove key. Close and lock doors. Check that room lamp turns
off.
4. Measure dark current. Is it 50mA or less? Refer toSC-22,
"OPERATION PROCEDURE OF CURRENT MEASUREMENT
PROBE FOR CONSULT-II".
NOTE:
Dark current stable time is different due to equipment and use of
the vehicle. If it is not 50mA or less after leaving for 1 minute, measure dark current again after leaving for
30 minutes or more.
If YES, GO TO 7. If NO, GO TO 5.
5. Remove and install fuses one by one. Search for the fuse that greatly changes dark current.
NOTE:
If dark current is greatly reduced when removing the fuse, and even if dark current is not greatly increased
when installing it again, the fuse circuit may be the cause.
6. Check that dark current changes when moving the suspect circuit harness. If dark current changes, check
harness for short. If dark current does not change, electronic unit in the circuit may not be entering the
energy-saving mode when it turns OFF. If it does not enter the energy-saving mode, replace electronic
unit.
7. No malfunction for alternator and electrical equipment. Electric load may be larger than alternator generat-
ing ability. Check the customer's usage.4 - Ground : 12V or more
