Battery, Starter, & Alternator Repair in San Marcos, CA

Your car’s electrical system relies on three key components—the battery, starter, and alternator—to keep it running smoothly. At Knight’s Automotive, we provide expert battery, starter, & alternator repair in San Marcos, CA, ensuring your vehicle stays powered and ready to go when you need it most.

The Role of the Battery

The battery is the heart of your car’s electrical system, supplying power to start the engine and run accessories like lights and radio. Over time, batteries lose their ability to hold a charge, especially in extreme weather conditions. If you’re dealing with slow cranking or dim headlights, it may be time for a replacement or a diagnostic check.

Starter Problems and Solutions

The starter is responsible for getting your engine running. When the starter begins to fail, you may hear clicking sounds when turning the key or experience a complete lack of response. Faulty solenoids or worn-out gears are common culprits, and our technicians are equipped to repair or replace these components with precision.

Alternator Function and Repairs

While the battery provides initial power, the alternator generates electricity to keep the engine running and recharge the battery. Signs of a failing alternator include flickering dashboard lights, a dead battery, or unusual noises under the hood. Our team can quickly diagnose and fix alternator problems to keep your electrical system functioning properly.

Comprehensive Testing and Repairs

At Knight’s Automotive, we use advanced diagnostic tools to assess the condition of your battery, starter, and alternator. From testing voltage output to checking for damaged wiring, we ensure no detail is overlooked. Whether you need a simple battery replacement or a more complex starter or alternator repair, we deliver reliable solutions.
