Lexus OEM Alternators

Your Lexus car or SUV relies on the alternator to provide electricity for many parts and systems. In fact, it's one of the most essential components in the charging system. How it works is simple. It takes the mechanical energy produced by the engine and transforms it into electricity.

How Alternators Work

The crankshaft takes the vertical motion of the engine pistons and converts it into rotary motion. That moves a belt attached to a pulley located on your rotor shaft. Inside the rotor shaft, magnetic coils get agitated by the motion and produce a magnetic field. That's then captured as AC power by a rectifier, which then converts it into the DC power your Lexus uses. A voltage regulator manages the power and uses it to charge the battery and operate such parts as your windows, wipers, entertainment system, and more.

How to Spot a Bad Alternator

Alternators, even the best ones, can go bad. If that happens, your battery is left as the sole electricity source for all systems and parts – meaning it will quickly drain and leave you stranded. Replace yours as soon as you can if you experience any of the following symptoms:

• Dim or flickering headlights
• Your sound system acts up
• The power windows quit operating
• Whining noises coming from your engine
• The battery keeps dying
