SQR484F CHARGING SYSTEM

GENERAL INFORMATION

Description

Alternator is a key component of the charging system. It is a device that converts mechanical energy into
electrical energy and generates DC voltage through a rectifying circuit, as one of main power sources of the
vehicle. The alternator operates as a complete assembly. If alternator fails for any reason, the entire unit must
be replaced.

Alternator Operation

Alternator is a silicon rectifying alternator, which mainly consists of rotor, stator and rectifier.
When direct current flows to the rotor winding, rotor claw establishes magnetic field to produce alternating
induced electromotive force. The stator is installed on the outside of the rotor, and it is secured together with
the front and rear end covers of alternator. When the alternator rotor is rotated by drive belt, magnetic pole
lines cut the stator winding, causing a change in the magnetic flux of the stator winding; thus, the stator
winding generates alternating induced electromotive force, producing alternating current. The three-phase
alternating current generated by alternator is converted to direct current from alternating current by rectifier,
and the direct current is transmitted to the vehicle electrical system and battery.

DIAGNOSIS & TESTING

Problem Symptoms Table

Charging System Charging Voltage Inspection

1. Leave vehicle under no load test condition and idle the engine. Measure battery voltage with digital

multimeter.
Standard voltage: 14.1 - 14.7 V
If result is not as specified, replace alternator (

See page 16-10

).

2. Leave vehicle under load test condition and idle the engine. Measure battery voltage with digital

multimeter.
Load test condition:
 Set headlight to high beam;
 Turn on blower and adjust blower speed to the highest;
 Turn on "A/C" switch;
 Turn cold and hot switch to adjust temperature of outlet to the highest.
Standard voltage: 14.1 - 14.7 V
If result is not as specified, replace alternator (

See page 16-10

).
