When your dashboard lights flicker or your car struggles to start, it’s not always your battery that’s to blame — your alternator could be the culprit.

Your vehicle’s alternator is one of the most important components under the hood. It powers your electrical systems and keeps your battery charged while you drive. Without it, your car won’t stay running for long. That’s why our team at Tower Auto Repair provides reliable, precise, and affordable alternator service to keep you safely on the road.
Understanding How Your Alternator Works
Your alternator is a generator that converts mechanical energy from your engine into electrical energy. It charges the battery and provides power to the vehicle’s systems — everything from your headlights and air conditioning to your dashboard display and power windows.
Key functions of your alternator include:
- Charging the battery while the engine runs.
- Powering all vehicle electronics and accessories.
- Maintaining consistent voltage to prevent electrical surges.
- Supporting the starter system by keeping the battery fully charged.
If your alternator begins to fail, it can drain your battery and eventually cause your engine to stall. That’s why regular inspection and maintenance are essential for a reliable vehicle.
Common Signs You Need Alternator Repair
A failing alternator can cause a variety of electrical problems — and if ignored, it can leave you stranded with a dead battery. Recognizing the signs early can help prevent costly repairs later.
Look for these warning signs:
- Dimming or flickering headlights – A weak alternator can’t maintain consistent voltage output.
- Battery warning light – If the light stays on after starting, it’s often an alternator problem.
- Dead or weak battery – Even a new battery will drain quickly if the alternator isn’t charging properly.
- Strange noises – Squealing or grinding sounds may indicate a worn-out alternator belt or bearings.
- Electrical issues – Power windows or radio cutting out can signal low voltage.
- Car stalls while driving – A failing alternator can cause the engine to shut off mid-drive.
If you notice any of these symptoms, visit Tower Auto Repair immediately for a complete alternator diagnostic test.

The Connection Between Your Alternator, Battery, and Starter
Your alternator, battery, and starter form a three-part system that works together to keep your car running reliably.
- The battery provides the initial power to start the engine.
- The starter uses that energy to crank the engine.
- The alternator recharges the battery while supplying power to the vehicle.
If one of these components fails, the others are affected. That’s why we always check your full charging and starting system when performing alternator service — including a starter repair or new battery check if needed. This ensures your car’s electrical system is balanced and dependable.

A little maintenance can go a long way in preventing alternator issues. With Dawsonville’s changing weather and frequent short trips, your alternator can face extra strain.

Frequently Asked Questions (FAQs) About Alternator Service & Replacement
Q: How long does an alternator last?
A: Most alternators last 80,000 to 150,000 miles, depending on driving conditions and maintenance.
Q: Can I drive with a bad alternator?
A: Not for long. A bad alternator won’t charge the battery, and once the battery dies, your car will stall.
Q: How do I know if it’s my alternator or battery causing the issue?
A: If your car starts but dies shortly after, it’s likely the alternator. If it won’t start at all, it may be the battery. Our diagnostics can confirm the cause.
Q: Can a bad alternator ruin a new battery?
A: Yes. A failing alternator can overcharge or undercharge a new battery, drastically reducing its lifespan.
Q: How much does alternator repair cost?
A: Prices vary based on your vehicle’s make and model, but Tower Auto Repair provides upfront quotes before any work begins.
