GENERAL INFORMATION
INTRODUCTION
The battery (Fig. 1) stores, stabilizes, and delivers
electrical current to operate various electrical sys-
tems in the vehicle. The determination of whether a
battery is good or bad is made by its ability to accept
a charge. It also must supply high-amperage current
for a long enough period to be able to start the vehi-
cle. The capability of the battery to store electrical
current comes from a chemical reaction. This reac-
tion takes place between the sulfuric acid solution
(electrolyte) and the lead +/- plates in each cell of the
battery. As the battery discharges, the plates react
with the acid from the electrolyte. When the charging
system charges the battery, the water is converted to
sulfuric acid in the battery. The concentration of acid
in the electrolyte is measured as specific gravity
using a hydrometer. The original equipment (OE)
battery is equipped with a hydrometer (test indica-
tor) built into the battery cover. The specific gravity
indicates the battery's state-of-charge. The OE bat-
tery is sealed and water cannot be added.
The battery is vented to release gases that are cre-
ated when the battery is being charged and discharged.
The battery top, posts, and terminals should be cleaned
when other under hood maintenance is performed.
When the electrolyte level is below the top of the
plates, Yellow/Clear in the test Indicator, the battery
must be replaced. The battery must be completely
charged, and the battery top, posts, and cable clamps
must be cleaned before diagnostic procedures are per-
formed.

GENERAL INFORMATION
INTRODUCTION
The starting system (Fig. 1) and (Fig. 2) has:
²Ignition switch
²Starter relay
²Park/Neutral Starting Back-Up Lamp Switch
with automatic transmissions
²Clutch Interlock/Upstop Switch with manual
transmissions
²Powertrain Control Module (PCM) for double
start over ride
²Wiring harness
²Battery
²Starter motor with an integral solenoid
These components form two separate circuits. A
high amperage circuit that feeds the starter motor up
to 300+ amps, and a control circuit that operates on
less than 20 amps.
The Powertrain Control Module (PCM) controls a
double start over ride safety that does not allow thestarter to be engaged if the engine is already run-
ning.
SUPPLY CIRCUIT AND CONTROL CIRCUIT
The starter system consists of two separate cir-
cuits:
²A high amperage supply to feed the starter
motor.
²A low amperage circuit to control the starter
solenoid.
DESCRIPTION AND OPERATION
STARTER MOTOR
The starter is a permanent magnet starter motor.
The fields have six permanent magnets. A planetary
gear train transmits power between starter motor
and pinion shaft. The starter provides mechanical
torque to rotate the crankshaft at an RPM (crank
speed) necessary for self-sustained spark/ignition.Fig. 1 Starting System Components - Automatic

DESCRIPTION AND OPERATION
CHARGING SYSTEM
DESCRIPTION
The charging system consists of:
²Generator
²Electronic Voltage Regulator (EVR) circuitry
within the Powertrain Control Module (PCM)
²Ignition switch (refer to the Ignition System for
information)
²Battery (refer to the Battery for information)
²Battery temperature sensor
²Wiring harness and connections (refer to the
Wiring for information)
OPERATION
The charging system is turned on and off with the
ignition switch. When the ignition switch is turned to
the ON position, battery voltage is applied to the
generator rotor through one of the two field termi-
nals to produce a magnetic field. The generator is
driven by the engine through a serpentine belt and
pulley arrangement.
The amount of DC current produced by the gener-
ator is controlled by the EVR (field control) circuitry,
contained within the PCM. This circuitry is con-
nected in series with the second rotor field terminal
and ground.
Temperature data, along with data from monitored
line voltage, is used by the PCM to vary the battery
charging rate. This is done by cycling the ground
path to control the strength of the rotor magnetic
field. The PCM then compensates and regulates gen-
erator current output accordingly and to maintain
the proper voltage depending on battery tempera-
ture.
All vehicles are equipped with On-Board Diagnos-
tics (OBD). All OBD-sensed systems, including the
EVR (field control) circuitry, are monitored by thePCM. Each monitored circuit is assigned a Diagnos-
tic Trouble Code (DTC). The PCM will store a DTC in
electronic memory for any failure it detects.
GENERATOR
DESCRIPTION
The generator is belt-driven by the engine. It is
serviced only as a complete assembly. If the genera-
tor fails for any reason, the entire assembly must be
replaced.
OPERATION
As the energized rotor begins to rotate within the
generator, the spinning magnetic field induces a cur-
rent into the windings of the stator coil. Once the
generator begins producing sufficient current, it also
provides the current needed to energize the rotor.
The Y type stator winding connections deliver the
induced AC current to 3 positive and 3 negative
diodes for rectification. From the diodes, rectified DC
current is delivered to the vehicles electrical system
through the generator, battery, and ground terminals.
Noise emitting from the generator may be caused
by:
²Worn, loose or defective bearings
²Loose or defective drive pulley
²Incorrect, worn, damaged or misadjusted drive
belt
²Loose mounting bolts
²Misaligned drive pulley
²Defective stator or diode
²Damaged internal fins
ELECTRONIC VOLTAGE REGULATOR
DESCRIPTION
The Electronic Voltage Regulator (EVR) is not a
separate component. It is actually a voltage regulat-
ing circuit located within the Powertrain Control
