Description
Symptoms of alternator problems
Battery warning light Battery-shaped warning lightThe most common symptom of a problem with your vehicle's charging system is a battery-shaped warning light or the "CHARGE" icon that comes on while driving. Normally this warning light should come on when you turn on the ignition, but should disappear as soon as the engine is started. If it stays on, there is a problem with your charging system.
The charging system warning light doesn't point directly to a failed alternator, although alternator problems are very common. Your mechanic will need to do further testing to pinpoint the defective part.
Another symptom of a weak charging system is when the dash lights and headlights dim at idle, but become brighter when the engine is revved. This problem could be caused not only by a weak alternator, but also by a failing battery, poor connection at the battery terminals or a loose serpentine belt.
A whining/buzzing noise coming from the alternator is another symptom of alternator troubles. In some cars, it could be caused by a noisy alternator bearing. In some Jeep/Chrysler vehicles, a bad alternator decoupler pulley could cause the same noise.
What is an Alternator?
The primary function of an alternator is to work jointly with the battery to supply energy to the electrical components, i.e., lights, fan, windshield wipers, etc. It changes the alternating current into a direct current and regulates the voltage to meet the required minimum power for each unit.
What is the voltage regulator of an alternator?
The voltage regulator is a part that controls the amount of power supply from the alternator to the battery. It controls the charging process as it’s designed with various functions and work depending on their applications. The rectifier is used to convert alternating current (DC) produce to direct current (DC) during the charging process.
