- Description The Alternator has eight built-in diodes, each rectifying AC current to DC current.Therefore, DC current appears at alternator "B" terminal.In addition, the charging voltage of this alternator is regulated by the battery voltage detection system.The alternator is regulated by the battery voltage detection system. The main components of the alternator are the rotor, stator, capacitor brushes, bearings and V-ribbed belt pulley. The brush holder contains a built-in electronic voltage regulator.

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


- Circuit Diagram

   

• 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.

- Removal and Installation

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.

Alternator B-terminal cable mounting nut :18.6 - 24.5 N.m (1.9 - 2.5 kgf.m, 4.1 - 5.5 Ib-ft)

4.Loosen the mounting bolts (A).

Alternator lower bolt :29.4 - 41.2 N.m (3.0 - 4.2 kgf.m, 21.7 - 30.4 Ib-ft)

5.Remove the alternator (A).

6.Install in the reverse order of removal.

- Disassembly

1.Remove the rear cover (A).

2.Remove the mounting bolts (A) and the regulator assembly.

   

• When installing, replace with new OAP cap.

3.Remove the OAP cap.

   

• When installing, replace with new OAP cap.

4.Remove the OAP pulley (A) using the special tool (09373-27000).

5.Remove the rectifier assembly (A) after disconnecting the stator leads.

6.Remove the 4 through bolts (A).

7.Disconnect the rotor (A) and bracket (B).

8.Install in the reverse order of removal.

- Reassembly

1.Reassemble in the reverse order of disassembly.

   

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

- Inspection [Rotor]

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.

[Stator]

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.

Hyundai Accent (HC) (2017 - 2022) Service Manual: Driver Airbag (DAB) Module and Clock Spring

- Description • Driver Air Bag (DAB)DAB is installed in the steering wheel, and electrically connected to the SRSCM via clock spring. It is deployed during frontal impact to protect the driver. • Clock SpringClock spring delivers actuation signal, generated by the sensors installed in the front and right/left sides of a vehicle, to the inflator (gas generator) of the driver air bag module via internal cable.
