Generators & Regulators: Description: Notes

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 10-amp fuse (No. 33 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 "S" detecting the input voltage. On models equipped with all-wheel drive, the charging circuit is protected by the 120-amp fusible link. On all models, the generator is grounded to the engine block.

With the ignition switch in the "ON" or "START" position; power is supplied through 10-amp fuse No. 14, located in the fuse block (J/B), to combination meter terminal No. 7 for the charge warning lamp

Ground is supplied to terminal No. 2 of the combination meter through terminal "L" of the generator and to generator terminal "E" (FX45), or through body ground (FX35), through body ground "E304" (FX45). 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.
