Charging System: Description and Operation

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 S through:
- 80 A fusible link [letter a, located in the fuse and fusible link box (with KA24DE engine)] or
- 100 A fusible link [letter a, located in the fuse and fusible link box (with VG33E engine)] and
- 7.5 A fuse (No.36, located in the fuse and fusible link box).

Generator terminal B supplies power to charge the battery and operate the vehicle's electrical system. Output voltage is controlled by the IC regulator at generator terminal S detecting the input voltage. The charging circuit is protected by the 80 A fusible link (with KA24DE engine) or the 100 A fusible link (with VG33E engine). Ground is supplied to generator terminal E through body ground E203 (with KA24DE engine) or body ground A1 (with VG33E engine).

With the ignition switch in the ON or START position, power is supplied
- through 10 A fuse [No.11, located in the fuse block (J/B)]
- to combination meter terminal 17 for the charge warning lamp.

Ground is supplied to combination meter terminal 43 through generator terminal L. 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.
