Diagnosis & Testing



The charging system includes a battery, an alternator with a built-in regulator, and the charging indicator light and wire. The generator has six built-in diodes (three positive and three negative), each rectifying AC current to DC current. Therefore, DC current appears at the alternator "B" terminal.

Visually check the alternator wiring and listen for abnormal noises. Check that the wiring is in good condition. Check for any abnormal noise from the alternator while the engine is running and that the belt is not worn or slipping.

The charging voltage of the alternator is regulated by the battery voltage detection system. The main components of the alternator are the rotor, stator, rectifier, capacitor brushes, bearings, and V-ribbed belt pulley. The brush holder contains the built-in electronic voltage regulator.
