OEM Subaru Alternators

Your alternator is an important part of your Subaru vehicle's charging system. Put simply, it's responsible for taking the mechanical energy produced by the engine and converting it into the electricity that most parts and systems use.

How Alternators Work

It all starts with the engine crankshaft. Turning the pistons' vertical motion into rotary motion, it powers a drive belt attached to a pulley located on your rotor shaft. The rotor shaft spins, which agitates magnetic coils that are located inside the rotor. The coils generate a magnetic field that a rectifier then captures as AC power. The rectifier converts that power into the DC power that your vehicle uses to charge the battery and power parts like the power windows, electronics, and wipers.

Over time, even the best alternator can go bad. When that happens, your battery is the only thing producing the electricity powering your systems. That's going to drain it, and quickly.

Recognize the Symptoms of a Bad Alternator

Signs of a failing alternator include:

• Dimming or flickering headlights
• The power windows stop working
• Your sound system acts up
• The battery keeps dying
• You hear a whining noise coming from your engine

The first thing you should do when you experience any of the above symptoms is to test your battery. If the voltage is below normal, your alternator is likely on its last legs even after a thorough charging. Replace yours before it fails completely to avoid getting stranded on the side of the road.
