What Does an Alternator Do and Why Is It Important?
Your vehicle's alternator plays a vital role in keeping everything running smoothly. It’s part of the charging system, working alongside the battery and voltage regulator to keep your car powered. As the engine runs, the alternator converts mechanical energy into electrical energy using a drive belt.
This power doesn’t just recharge the battery—it also keeps essential systems like your headlights, dashboard electronics, and heating operating while the engine is on.
Alternators are generally reliable and can last anywhere from 10 to 15 years, depending on driving habits and vehicle type. But once it fails, your car may only run for a short time on battery power before it comes to a halt—so early diagnosis and repair are key.

Car Alternator Repair and Replacement Services
Your car’s alternator is one of the most important parts of the vehicle. It’s responsible for generating an electrical charge that recharges the battery, which is critical for running the engine and accessories.

Signs Your Alternator Might Need Replacing
Flat Battery
Car batteries have a limited lifespan, and a dead battery usually means it’s simply time for a replacement. But flat batteries can also be a sign that something is wrong with the alternator. Our experienced technicians can diagnose the issue, identify whether it’s a problem with your battery or alternator, and then repair the problem.
Stalling Engine
If your engine stalls while driving, it can be due to an underperforming alternator. Car engines require small amounts of electricity while running. If your battery can’t provide that power, it’s a sign that something is wrong with the alternator. Our team will be able to conduct diagnostic tests and offer car alternator repairs to fix the issue.
Dim Lights
The lights in your car should provide a steady beam. If your headlights or dashboard lights are noticeably dim, or if they flicker while driving, this can be a sign that you need car alternator repair. If you notice this issue then it’s best to book an appointment sooner rather than later. That will allow us to repair the problem before you find yourself stuck with a car that won’t start.
Electrical Issues
An old or faulty alternator may still be able to provide enough power to start the car and run accessories like the lights. The tricky part is that you may experience other electrical issues, like problems with the windows or radio. These small things can indicate there’s something wrong with your alternator. You’ll usually need the help of an experienced auto electrician in these cases, as it can be challenging to diagnose the issue.
Should My Alternator Be Repaired or Replaced?
We typically recommend replacing a faulty alternator. Your alternator is a critical part of keeping your car running, and an old, damaged or malfunctioning alternator could leave you stranded. Replacing your alternator is a straightforward process, and it ensures you’ll never find yourself stuck on the side of the road.
In some cases, we may recommend repairing an alternator if it’s the more affordable option. The good news is that alternators are relatively simple devices. That means there are only a few potential faults in most cars, and we can usually source spare parts to carry out repairs.
You’ll need to talk to our technicians to figure out whether repair or replacement is the right choice for your car. We’ll assess your vehicle, test the alternator and make a recommendation as to whether it will be cheaper to repair or replace the part.

Frequently Asked Questions
How much does it cost to repair an alternator?
In Brisbane, the cost to repair an alternator typically ranges from $200 to $500, depending on the extent of the damage, your vehicle's make and model, and the parts required. In some cases, it may be more economical to replace the alternator altogether, especially if it's older or severely worn.
Is it worth it to fix an alternator?
Yes—repairing an alternator is often worth it, particularly if the issue is minor, such as worn-out brushes or a faulty bearing. Repairs can be significantly cheaper than a full replacement. However, if the alternator is nearing the end of its lifespan or has multiple failing components, replacement may offer better long-term reliability.
Can you jump a car with a bad alternator?
You can jump-start a car with a bad alternator, but it’s only a temporary solution. Once the battery drains again—which can happen quickly without a working alternator—the car will stall. If you suspect alternator failure, it’s best to get the vehicle checked and repaired as soon as possible to avoid being stranded.
