What is an Alternator, and Why Should You Change it Regularly?

An alternator is an essential car part that generates the electricity needed to power all electronics and accessories in your vehicle. It converts mechanical energy into electrical energy.

Your car's battery provides the initial power that gets your car started. Still, as soon as you switch on the ignition, the alternator takes over and generates enough energy to maintain the control required for your car's systems.

Besides your usual oil change, tire rotation, and fluid check-ups, you should also regularly check your alternator. Without regular maintenance, an old or worn-out alternator can cause your car to break down and increases the risk of electrical system failure.

What Are the Signs of Alternator Failure?

If your car's alternator is failing, you'll likely notice one or more of the following signs:

Headlights dimming or brightening:

If you notice your headlights dimming or brightening while driving, this is likely a sign that your alternator isn't providing the right amount of power.

Car won't start:

Besides being low in oil, a dead battery is one of the most common reasons your car won't start. If this happens, it's a sign that your alternator may fail.

Dead battery:

If your battery is dead, and you've already checked all the other possible causes, it could be a sign that your alternator isn't working correctly

Slow engine cranking:

If it takes much longer than usual for your engine to crank, this could be a sign that your alternator is failing.

Electrical systems dying or malfunctioning:

If your car's electrical systems, such as the air conditioning or radio, fail or malfunction, it could be a sign that your alternator isn't working correctly.

Lack of power when accelerating:

When your alternator fails, you may notice a lack of control. Your brakes may also feel weaker when you press down.

Your alternator and brakes are the most critical components in your car's electrical system. Brake repair and alternator replacement should never be put off for too long.

Stalling or sluggish engine performance:

Battery warning light on the dash:

Your battery warning light should not be on while driving. This could indicate that your alternator isn't working correctly if it is.

If your car shows any of these signs, it's time to check your alternator. Don't postpone having it checked or replaced.
