Top Alternator Replacement related questions

One of the easiest ways to detect a faulty alternator is through the indicator light (the code varies according to different vehicles). If it turns on, get it checked by a trusted electrician right away. Some indications also include sudden weird noises or a burning smell coming from the engine, and irregular operation of other electrical components.

Some manufacturers suggest a total alternator replacement after 100,000 to 150,000 miles. If you detect any irregularities with your electrical system, your tasker can also help you test the alternator and have it replaced once it's broken or no longer usable.

The entire replacement process usually takes about two hours, but it may take longer if it's more rooted in the engine, or if there are more electrical and belt issues that must be resolved as well.

Airtasker is the best place to find an alternator replacement specialist near you. All you have to do is post a task with your specific needs, along with your ideal alternator replacement cost, and you'll instantly hear back from our expert auto technicians who are available to lend a helping hand whenever and wherever!

Suggested reads about Alternator Replacement

What does an alternator replacement service include?

The function of the alternator is simple: supply power to the battery and keep the electronics running. Otherwise, your vehicle will stop working. Your car will send a series of signals that will indicate a failing alternator, including a whirring noise coming from your engine and the smell of burning rubber. If you're starting to notice these warning signs, then you may need to get your alternator replaced immediately. 


Mobile Alternator Replacement
At Airtasker, you can find trusted alternator specialists and other mobile mechanics near you, offering you a convenient way of repairing your car's alternator or replacing it as needed. You don't have to risk fixing it yourself or stress over finding a car repair shop in your neighbourhood. Your mobile alternator replacement specialist will go where you are and replace your car's alternator in no time.

Disconnecting the Battery

Before the actual replacement, your Tasker will first disconnect your car battery for safety purposes. Skipping this step might trigger a live wire as they're removing or replacing the alternator, and can cause further damage as well. They will only remove the negative cable while the positive one remains attached.


Removing the old alternator
Most alternators are usually found on top of the engine. Some alternators, however, are positioned deeper in the engine and removal might take a little longer. After locating the faulty alternator, your Tasker will detach the serpentine belt or v-belt, as well as the bolts, wirings, and cables connected to the engine. After which, the old alternator will be safely removed.

Inspecting the new alternator
Your new alternator must have the same mounting holes and wire connectors as the old one. If you're hesitant or worried about buying the wrong alternator, you can always arrange for your Tasker to help you find the right one for your vehicle.

Positioning and Installing the Alternator
Your specialist will install the new alternator where the old one was placed. This process is simple—match the bolt holes, then put the battery, serpentine belt, cables, and wirings back to where they were previously. Your Tasker will then turn on your engine to check if the replacement alternator is working correctly. You can also request for a quick test drive to make sure that the process was successful.

Car won't start battery dies out

Alternator might need to be replaced or i need multimeter scan for car

$350

San Diego CA 92111, USA

Jan 13th 2026

I might or might not need a diagnostic I think I know what the problem is and might need a quote, but i’m no professional of course. I also have a video of the incident that occurred. my entire electrical system started to glitch out as soon as i got off the freeway to go home. My steering wheel started locking on me and the car eventually shut down completely. i got it jump started, 2 minutes later the car completely died so i asked my grandfather since he has experience in being a mechanic and it can most likely be the alternator. The alternator drained the battery so I went to get a new battery so that i can get the alternator fixed because i'm aware the new battery will just be drained if i try it with the old alternator. I let the car run for a few minutes and the battery light stayed on for some time. I even tried using my own OBD Il scanner it shows no codes but the battery light is still there and that just worries me. I believe I really need my alternator replaced and that's all. If need be, I will buy an alternator part if that's easier, but i'd like both quotes with & w/out the part. Im not sure what it can really be, because when i got the new battery the light keeps flickering on & off and my scanner is not showing anything is wrong with the car when i know it is. I asked my grandfather to check the Alternator "Excite" Wire but he had to travel back home. He told me to ask around for whatever shop I go to check the wire since the small plug on the back of the alternator can sometimes get brittle or loose. If that plug isn't making a solid connection, a brand new alternator still won't charge the battery.

The battery light came on the day before. The battery is 1 month old. I suspect a faulty alternator. I have a new alternator purchased, but need a mechanic with a breaker bar to removed the last bolt from the old alternator and help me install the new one. Looking to do that work around 0900 on Jan 3.

Rebuild my alternator 2009 Audi a4

$200

Los Angeles CA 90036, USA

Dec 28th 2025

I have a 2009 Audi A4 2.0T (4-cylinder) with a confirmed alternator / charging system issue. I’m looking for a mobile mechanic who can come to my location to diagnose the charging system and either: • remove and install a rebuilt or remanufactured alternator, or • remove the alternator so it can be rebuilt by an auto-electric shop, then reinstall it. I am open to supplying the alternator myself (rebuilt/reman) if preferred. The car currently starts but does not reliably charge the battery. Please let me know: • total cost for labor • whether you install customer-supplied parts • estimated time on site Looking for the most cost-effective solution, not dealer pricing.
