When Alternators & Starters Fail

Most drivers notice charging or starting issues through subtle changes like dim lights or dramatic failures like a silent ignition. Because the battery, alternator, and starter work together, symptoms often overlap, making an accurate diagnosis essential. A weak battery can mimic other failures, so we test the entire system to avoid guessing and ensure we solve the real problem the first time.

Watch for these common signs that indicate it is time to contact our team:

Dashboard Warning: The battery light stays on or flickers while driving, indicating a potential charging system failure.
Dim Lights: Headlights or interior lights fade significantly when you slow down or idle at intersections.
Audible Clicks: You hear a single click or rapid clicking sounds when turning the key or pushing the start.
Sluggish Crank: The engine turns over very slowly or refuses to start despite the battery having a charge.
Electrical Lapses: Radios or power windows cut in and out, especially when the vehicle is under electrical load.

If these symptoms sound familiar, our technicians will test the whole system to pinpoint the root cause. We explain whether you need alternator installation or starter replacement, walking you through our findings so you understand exactly why a specific repair was recommended.

Trust us to pinpoint the real issue quickly. Schedule your inspection online or call us at (815) 426-9532 for expert care.

Our Diagnostic & Repair Process

At Christian Brothers Automotive Lockport, we solve starting issues by first listening to you. We ask specific questions about when the problem occurs and what symptoms you notice. These details, combined with a visual inspection, allow our technicians to focus on the most likely causes while ensuring the entire system is tested thoroughly.

Accurate Testing & Honest Consultation

We use professional-grade equipment to test the battery, charging system, and starter circuit. We measure alternator output under load and evaluate starter current draw. This provides objective data to compare against manufacturer specifications, ensuring we identify the root cause rather than relying on guesswork or quick visual checks.

Once testing is complete, we review the results with you clearly. We explain exactly what failed and provide a transparent estimate covering parts and labor. We encourage your questions and never proceed without your approval, ensuring you understand the necessary repairs and feel confident in your decision.

Precision Repair & Final Verification

Our repairs follow your vehicle manufacturer’s specific guidelines. For alternator installation, we ensure proper belt tension and secure connections. During car starter replacement, we also check for contributing factors like oil leaks or heat damage. This attention to detail prevents recurring issues and protects your electrical system.

After the work is finished, we re-test the system to guarantee reliable operation before returning your keys. We review the completed services, explain your warranty coverage, and offer maintenance guidance. Our goal is for you to leave with a dependable vehicle and total peace of mind.

FAQs

Q. "Why is the alternator important?"

The alternator helps the battery maintain power. As the car is driving, it’s gaining power from the engine. During this time, the alternator is charging the battery. When the car stops running, the charge from the alternator allows the battery to continue providing power to the car.
Q. "What does the alternator do?"

As an alternate source of power, the alternator helps many features in the car run. It helps your air conditioning maintain proper airflow, powers the radio, and turns on the headlights, among other things. It can also add power to the engine.
Q. "Where is the alternator located?"

You’ll typically find the alternator near the front of the engine, bolted in with two brackets. One is adjustable (to allow for drive belt-tightening) while the other is fixed.
Q. "What are some signs that my starter is going bad?"

Some common symptoms that your starter is going bad or is dead include: clicking or other odd noises, lights working in your car but the engine won't turn, taking more than one attempt to start, or smoke coming from the hood.
Q. "Do you offer a warranty?"

As part of our Nice difference.® commitment to providing our customers the best auto service experience possible, we also offer a3-year/36,000-mile warranty on all the work that we do. We offer this warranty at every Christian Brothers Automotive nationwide, and it will be honored at any location, regardless of which branch did the initial work.
Q. "What is a Digital Vehicle Inspection?"

With a complimentary Digital Vehicle Inspection (DVI) on every visit, you’ll see firsthand photos of your vehicle from under the hood. We’ll let you know if everything is functioning properly or if there are any areas of concern. You can even approve or deny our service recommendations, all straight from your smartphone, or you can, of course, give us a call and we’ll explain our findings in further detail.
