What is an alternator?

An Alternator is a generator used in automobiles to charge the battery while the engine is running. Alternator powers the electrical components of the car, like interior and exterior lights, and the instrument panel.

How does an alternator work?

The alternator has three components: stator, rotor, and diode. A rotor is a group of magnets, spinning inside a coil of copper wires called the stator. The spinning of magnets at high speed creates electricity in copper wires through the electromagnetic effect which is conducted to the diode which charges the battery.

What is a bad alternator?

The alternator is a hard-working part of a car. It takes care of all the electrical systems and the battery when the engine is running. Alternators get dirty and are subject to stress from the heat and cold. Because of this, internal parts of an alternator tend to wear out with time, which causes bearing failure. A bad alternator can cause battery failures and create problems in the ignition process.

How to know if you have a bad alternator?

A bad alternator can be identified by these symptoms:
1. Dimming/pulsating headlights while accelerating or revving up the engine.
2. A loud grinding noise or squealing engine are often symptoms of a bearing failure in alternators.
3. Failure to power all the electrical components, like headlights and power windows.

Next time you encounter any of these symptoms, get your car to a competent mechanic. A healthy alternator will keep you and your car safe on the road.
