System Description
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 (S) (ZD30DDTi engine models) through:
I10A fuse (No. 31, located in the fuse and fusible link box).
Terminal B supplies power to charge the battery and operate the vehicle's electrical system. Output voltage
is controlled by the IC regulator at terminal 4 (S) detecting the input voltage (ZD30DDTi engine models). The
charging circuit is protected by the 100A fusible link.
The alternator is grounded to the engine block.
With the ignition switch in the ON or START position, power is supplied
I through 10A fuse [No. 12, located in the fuse block (J/B)]
I to combination meter terminal 28 for the charge warning lamp.
Ground is supplied to terminal 2 of the combination meter through terminal 1(L) (TD27Ti engine models) or
3(L) (ZD30DDTi engine models) of the alternator. With power and ground supplied, 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.
If the charge warning lamp illuminates with the engine running, a malfunction is indicated.

I to daytime light control unit terminal 7 and
I to lighting switch terminal 8.
With the ignition switch in the ON or START position, power is supplied
I through 10A fuse [No. 11, located in the fuse block (J/B)]
I to daytime light control unit terminal 12.
With the ignition switch in the START position, power is supplied
I to daytime light control unit terminal 8.
Ground is supplied to daytime light control unit terminal 10 through body grounds M33 and M754.
HEADLAMP OPERATION (DAYTIME LIGHT CANCEL OPERATION)
When the lighting switch is turned to the 1st or 2nd position, power is supplied
I through lighting switch terminal 12,
I to daytime light control unit terminal 3.
Then daytime light will be canceled. And the lighting system operation will be the same as no daytime light
system.
DAYTIME LIGHT OPERATION
With the engine running and the lighting switch in the OFF position, power is supplied
I from alternator terminal 1
I to daytime light control unit terminal 2,
I through daytime light control unit terminal 9
I to terminal 2 of headlamp LH,
I through daytime light control unit terminal 11
I to terminal 2 of headlamp RH and
I through daytime light control unit terminal 6
I to tail lamp and illumination.
Ground is supplied to terminal 3 of each headlamp through body grounds F36, F47 (LH) and M33, M754 (RH).
