Frequently Asked Questions
What does the alternator do in my car?
Your alternator is responsible for generating electrical power while the engine runs. It charges your battery and powers key systems like your headlights, infotainment, air conditioning, and dashboard electronics. If your alternator fails, your battery will quickly drain, causing your vehicle to lose power or fail to start. It’s vital for keeping everything electrical running smoothly while you’re on the road.
What are the signs that my alternator needs to be replaced?
Watch out for a battery warning light on your dash, flickering or dim headlights, a battery that won’t hold a charge, odd noises from under the bonnet, and erratic behavior from electrical systems. These issues usually point to a charging problem. If caught early, you can avoid breakdowns and damage to other vehicle components. It’s one of those things that is best caught early to prevent even worse issues and higher expenses down the road.
Can I still drive if my alternator is failing?
Only for a short time. When your alternator isn’t functioning, your car relies entirely on battery power, which runs out quickly. Once depleted, your engine will stall and won’t restart. It’s safer to get your charging system inspected right away. Continuing to drive can also affect power steering, braking, and other essential functions. Call us and book in with the trusted Autospark team as soon as you start noticing any issues.
How long does an alternator replacement take?
Most alternator replacement services take between 1 to 2 hours, depending on your vehicle’s design. At Autospark, we focus on both speed and precision, ensuring the new alternator is installed properly and the charging system is fully tested before you leave. We aim to get you back on the road without unnecessary delay.
Can a bad alternator damage my battery?
Yes. A faulty alternator can overcharge or undercharge your battery, which may reduce its lifespan or lead to failure. Leaving it unchecked can also affect other systems that rely on stable voltage. Prompt replacement helps protect your battery, improve reliability, and avoid the cost of additional repairs down the line.
