Alternator functions as the heart of the charging system.It produces alternating current (AC), which is converted to Direct Current (DC) by a six diode rectifier. Thus alternator generates the power required to keep the battery fully charged and to operate every electrical unit inside a vehicle.
Symptoms that you can watch to detect any alternator problems:
- Alternator fails to charge (Indicator light may be on)
- Low Charging Rate (Battery may be running down)
- Excessive charging rate (Battery may have water level low)
- Battery fails to holds charge (or battery may be dead)
- Alternator Noise
