HOW DOES AN ALTERNATOR WORK?

The alternator is connected to the engine’s crankshaft via the serpentine belt. As the engine runs, the alternator spins, generating alternating current (AC), which is then converted to direct current (DC) by a rectifier. This stored electrical energy in the battery powers everything from starting the engine to charging your phone. Over time, alternators wear out and can cause major electrical issues. Regular alternator inspections can help detect early signs of failure before they leave you stranded.

POPULAR QUESTIONS:

  • What is the role of the alternator in my vehicle?

    The alternator is responsible for generating electricity to recharge your battery and power all electrical components in your car while the engine is running. It works in conjunction with the battery to keep your headlights, dashboard instruments, air conditioning, and other electrical systems functioning properly. Without a working alternator, your battery will quickly drain, and your car may not start.

  • How long does an alternator last?

    Most alternators last between 7 to 10 years or 80,000 to 150,000 miles, but lifespan varies based on driving conditions and electrical usage. Regular inspections and maintenance can extend its life.

  • How does the alternator affect engine performance?

    Your alternator powers the spark plugs, fuel injectors, and engine control systems. If it fails, your car may experience rough idling, misfires, or stalling due to inconsistent power delivery.

  • What are the signs of a bad alternator?

    A faulty alternator can cause hard starts, electrical failures, and battery drain. Here are some common warning signs:

    • Dead battery or slow starts – The battery won’t recharge properly
    • Dimming or flickering headlights – Inconsistent power output
    • Car dies after jump-starting – Indicates the alternator isn’t replenishing battery power
    • Grinding or squealing noise under the hood – A worn alternator bearing
    • Warning lights on the dashboard – Often a battery or charging system alert
  • Can I drive with a bad alternator?

    It’s not recommended. A failing alternator can cause unexpected stalling while driving, leaving you stranded. If you experience battery issues, dim lights, or strange noises, schedule an inspection as soon as possible.

  • When should I replace my alternator?

    If your vehicle shows any symptoms of alternator failure, it’s important to get it checked before your battery completely dies. At Liquid Lube & Wash, our expert technicians will test, diagnose, and replace your alternator quickly and efficiently so you can drive with confidence.

  • What’s the difference between the alternator and the battery?

    The battery starts your car, but the alternator keeps it running by recharging the battery and powering electrical systems. A dead alternator means the battery will drain quickly, leaving you stranded.
