GENERAL INFORMATION (Continued)
Downloaded from www.Manualslib.com manuals search engine 8W-20 CHARGING SYSTEM
DESCRIPTION AND OPERATION
CHARGING SYSTEM
The charging system is an integral part of the bat-
tery and starter systems. Since all of these systems
work together, any diagnosis and testing should be
done in conjunction.
The charging system is protected by a 12 gauge
fusible link located in the A11 circuit. This fusible
link is between the generator and the starter.
The generator ground is provided through a case
ground in the generator to its attaching bracket. This
generator uses a voltage regulator internal to the
Powertrain Control Module (PCM).
When the vehicle is running, battery voltage is
applied to the generator field terminal through the
A142 circuit. This circuit is the output from the con-
tact side of the Automatic Shut Down (ASD) relay.
The ground, or voltage regulated side, of the genera-
tor field is controlled by the K20 circuit which con-
nects to cavity 4 of the PCM connector.
When there is current present in the field, and the
rotor is turning, the stator in the generator produces
a B+ voltage that is supplied to the battery through
the A11 and A0 circuits. The A11 circuit is connected
to the output terminal of the generator and connects
to the engine starter motor battery feed terminal.
The A0 circuit is a direct feed line from the battery
and connects to the engine starter motor.
Grounding for the system is accomplished at the
battery negative terminal. These grounds connect to
the engine and body.
HELPFUL INFORMATION
²Inspect for a blown fusible link in the A11 cir-
cuit between the generator and the starter motor.
²For additional information on charging system
diagnosis, refer to the appropriate section of the ser-
vice manual.
