Hyundai Accent (HC): Charging System / Alternator

- Specification

1. Brush
2. Pulley
3. Rotor
4. Stator

• COM signal - When controlling the voltage generated, the ECM sends the target voltage data to the alternator via a LIN signal.

• B+ terminal - The output voltage from the generator travels to the battery via the B+ terminal.

1.Turn ignition switch OFF and disconnect the battery negative (-) terminal.

2.Remove the drive belt.(Refer to Engine Mechanical System - "Drive Belt")

3.Disconnect the air compressor connector (A) and the alternator connector (B), and remove the cable (C) from alternator "B" terminal.

• When reassembling OAP pulley, replace with new OAP cap.

1.Check that there is continuity between the slip rings (C).

2.Check that there is no continuity between the slip rings and the rotor (B) or rotor shaft (A).

3.If the rotor fails either continuity check, replace the alternator.

1.Check that there is continuity between each pair of leads (A).

2.Check that there is no continuity between each lead and the coil core.

3.If the coil fails either continuity check, replace the alternator.
