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 The voltage output is controlled by the IC regulator.

Power is supplied at all times to generator terminal 3 through
- 10 A fuse (No. 29, located in the fuse and fusible link box).

Power is supplied through terminal 1 to charge the battery and operate the vehicle's electrical system. voltage is monitored at terminal 3 by the IC regulator. The charging circuit is protected by the 120 A [letter a, located in the fusible link box (battery)].

Ground is supplied
- to generator terminal 5
- through body ground F5, and
- through the generator case to the cylinder block

With the ignition switch in the ON or START position, power is supplied
- through 10 A fuse [No. 3, located in the fuse block (J/B)]
- to combination meter terminal 28 for the charge warning lamp.
The IC regulator controls ground to terminal 38 of the combination meter through terminal 2 of the When the ignition is turned on and power becomes available at terminal 2, this "wakes up" the regulator. regulator monitors charge output and grounds terminal 2 or leaves it open depending on charge power and ground supplied, the charge warning lamp will illuminate. When the generator is providing voltage, 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.
