Description and Operation
Description
The AC generator has eight built-in diodes, each of which converts alternating current to direct current. Therefore, direct current appears at the generator B terminal. In addition, the charging voltage of this generator is regulated by the battery voltage sensing system. The main components of the generator are the rotor, stator, rectifier, brushes, bearings, and the poly-V belt pulley. The brush holder contains a built-in electronic voltage regulator.

Repair Procedures
Removal
- Turn the ignition switch OFF and disconnect the negative (-) battery terminal.
- Remove the air cleaner. (Refer to Engine Mechanical System - "Air Cleaner")
- Disconnect the generator connector (A) and the generator "B" cable (B) from the terminal.
Tightening torque: 13.7 - 17.7 N·m

- Remove the drive belt. (Refer to Engine Mechanical System - "Drive Belt")
- Remove the intake manifold. (Refer to Engine Mechanical System - "Intake Manifold")
- Remove the generator mounting bolts (A). Tightening torque: Generator upper mounting bolt: 29.4–41 N·m Generator lower mounting bolt: 21.6–32 N·m

- Remove the alternator (A).


Installation
- Install in the reverse order of removal.
- After installation, adjust the alternator belt tension. (Refer to Engine Mechanical System - "Drive Belt")
- Install the generator.
Disassembly
- Remove the rear cover (A).


- Remove the regulator assembly (A) after loosening the mounting bolts.


- Remove the OAP cover (A).

- Using SST (09373-27000), remove the OAP pulley (A).


- Remove the rectifier assembly (A) after disconnecting the stator wires.

- Loosen the through bolts (A).

- Separate the rotor (A) and housing (B).

Installation
- Assemble in the reverse order of disassembly.
Inspection
[Rotor]
- Check the slip rings (C) for continuity.

- Check that there is no continuity between the slip rings and the rotor (B) or the rotor shaft (A).
- If the rotor fails the continuity check, replace the generator.
[Stator]
- Check for continuity between each pair of wires (A).

- Make sure there is no continuity between each terminal and the coil core.
- If the coil fails the continuity check, replace the generator.
