If your vehicle’s electronic systems are malfunctioning or your battery light suddenly turns on, it could be a sign that your alternator is failing.

Whether you're commuting through Spring Valley, CA, El Cajon, CA, Santee, CA, La Mesa, CA, or Alpine, CA, a functioning alternator is essential for a safe and uninterrupted drive.

How Does an Alternator Work?

The alternator is a core component of your vehicle’s charging system, working alongside the battery and voltage regulator to supply power to critical systems like your air conditioning, lights, infotainment, and more. It gets its name from the alternating current (AC) it generates, which is converted into usable power for your car’s electrical components.

Located at the front of the engine, the alternator is driven by the crankshaft via a serpentine belt. It sends electricity to your battery and electrical system while your engine is running. If any part of this system fails, such as a frayed serpentine belt, faulty terminals, or a damaged voltage regulator, your alternator can’t charge the battery, and your car may lose power.

Your alternator includes:

• Front and rear vents for heat dissipation
• Multiple terminals for sensing voltage, connecting to the voltage regulator, and managing battery charging
• A direct role in powering essential vehicle electronics

If any of these components are compromised, your entire charging system could be at risk.

Signs Your Alternator Needs Replacement

Whether you drive a Toyota, Honda, Ford, Subaru, or another brand, the signs of a failing alternator are universal. If you notice any of the following issues, visit Banny Hom Automotive in El Cajon, CA for an inspection:

• Dashboard battery light is on: This is often your first warning. You may also see ALT or GEN lights depending on your make/model.
• Dim or flickering headlights: Slower window operation or glitchy backup cameras can also indicate a charging issue.
• Loose serpentine belt: If this belt becomes worn or loose, it will reduce alternator performance.
• Strange noises: Grinding, whining, or squealing sounds may signal internal component failure inside the alternator.
• Accessories not working properly: Radios, GPS units, and other electronics may stop functioning.
