Description



Specific to:

Nissan Sentra 2007-2012

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 3 through:



10A fuse [No. 26, located in the fuse block (J/B)].
 

Power is supplied through terminal 1 to charge the battery and operate the vehicle's electrical system. Output voltage is monitored at terminal 3 by the IC regulator. The charging circuit is protected by the 225A fusible link [letter a, located in the fusible link box (battery)].

Ground is supplied



to generator terminal 5
 
through body ground F5 (2.0L)
 
through body ground E62 (2.5L) and
 
through the generator case to the cylinder block
 

With the ignition switch in the ON or START position, power is supplied



through 10A fuse [No. 14, located in the fuse block (J/B)]
 
to combination meter terminal 2 for the charge warning lamp.
 

The IC regulator controls ground to terminal 32 of the combination meter through terminal 2 of the generator.

When the ignition is turned on and power becomes available at terminal 2, this "wakes up" the regulator. The regulator monitors charge output and grounds terminal 2 or leaves it open depending on charge output. With power and ground supplied, the charge warning lamp will illuminate. When the generator is providing sufficient 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.
