What Does An Alternator Do?
The alternator generates electricity while the engine is running and helps power your vehicle's electrical systems. It also recharges the battery while you drive.

Power windows
-
Radio and infotainment systems

Climate control systems

Vehicle computers and sensors
When the alternator fails, your battery may no longer recharge properly, eventually causing the vehicle to stall or fail to start.
What Does A Starter Do?
The starter motor is responsible for turning the engine over when you turn the key or press the start button.
Without a functioning starter, the engine cannot begin running.

FAQ's
How do I know if my alternator is failing?
A failing alternator may cause your battery warning light to turn on, dim headlights, electrical accessories to stop working properly, or difficulty starting your vehicle. If you notice these symptoms, our technicians can test your charging system to determine whether your alternator needs repair or replacement.
What are the signs of a bad starter?
Common signs of a failing starter include a clicking sound when you turn the key, slow or no engine cranking, intermittent starting problems, or the engine failing to start even though the battery is fully charged. Our team can diagnose the problem and recommend the proper repair.
Can a bad battery cause the same symptoms as a bad alternator or starter?
Yes. A weak battery, failing alternator, or faulty starter can all cause similar starting problems. That's why we perform a complete battery, charging system, and starter test before replacing any parts to ensure an accurate diagnosis.
How long does it take to replace an alternator or starter?
Most alternator and starter replacements can be completed the same day, depending on your vehicle's make, model, and parts availability. After diagnosing the issue, we'll provide an estimated repair time and keep you informed throughout the process.
Should I replace my battery when replacing my alternator or starter?
Not necessarily. If your battery passes our performance test and is in good condition, there is usually no need to replace it. However, if the battery has been damaged by a failing alternator or is near the end of its lifespan, we may recommend replacing it to help prevent future starting problems.
