Charging System: Description and Operation

CHARGING SYSTEM

System Description
The generator 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 generator terminal 4
- through 10 A 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 140 A fusible link (letter a , located in the fusible link box).

Ground is supplied:
- to generator terminal 2
- through body ground E203.

With the ignition switch in the ON or START position, power is supplied:
- through 10 A fuse [No. 14, located in the fuse block (J/B)]
- to combination meter terminal 24 for the charge warning lamp.

Ground is supplied to terminal 13 of the combination meter through terminal 3 of the generator. With power and ground supplied, the charge warning lamp will illuminate. When the generator 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 fault is indicated.
