CHARGING SYSTEM
CHARGING SYSTEM
PFP:00011
System Description EKS00316
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)
●through 10A fuse (No.34, located in the fuse and fusible link box)
●to alternator terminal B
●through 120A (Gasoline engine models) or 100A (Diesel engine models) fusible link (letter A, 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. The charging circuit is protected by
the 120A (Gasoline engine models) or 100A (Diesel engine models) link.
The alternator is grounded to the engine block.
With the ignition switch in the ON or START position, power is supplied
●through 10A fuse [No. 11, located in the fuse block (J/B)]
●to combination meter terminal 46 (LHD models) or terminal 59 (RHD models) for the charge warning
lamp.
Ground is supplied with power and ground supplied
●to terminal 64 (LHD models) or terminal 54 ( RHD models) of the combination meter
●through terminal 3 (L) of the alternator
●to terminal E of the alternator
●through body ground E30.
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.
