FAQ About Alternators
what does an alternator do?
An alternator is like the car’s power station. When your engine is running, the alternator spins and creates electricity. This electricity does two big jobs:
Keeps the battery charged – The battery is mainly for starting the car. Once the engine is on, the alternator takes over and keeps feeding energy back into the battery so it doesn’t go flat.
Runs all the electrical parts – Everything that needs power, like your headlights, air conditioning, power windows, wipers, and even the stereo, gets electricity from the alternator while you drive.
Without a working alternator, the battery would drain very quickly, and the car would stop running once the battery is empty.
how long does an alternator last?
An alternator will serve you for 7 to 10 years, or anywhere between 80,000 and 150,000 miles.
A few things can affect its lifespan:
- Driving conditions – Lots of short trips or stop-and-go traffic can make the alternator work harder.
- Electrical load – Using many electronics at the same time (AC, heated seats, sound system, lights, etc.) puts extra strain on it.
- Maintenance – A worn-out belt or loose connections can cause the alternator to fail sooner.
how to test alternator?
- Start the engine – Turn on the car and let it idle because the alternator only works when the engine is running.
- Check the battery voltage – Place a multimeter on the battery terminals with the engine running. A properly working alternator will usually keep the reading in the 13.8–14.8 volt range. If the number is much lower, it means the alternator isn’t supplying enough charge.
- Turn on electrical loads – Switch on the headlights, AC, and radio. The voltage should stay close to the same range (around 13.5–14.5 volts). If it drops a lot, the alternator could be weak.
- Listen and look – A failing alternator may make whining or grinding noises, or the dashboard battery light might glow.
signs of a bad alternator
Battery Light On – The battery or charging warning light shows up on the dashboard.
Weak or Dead Battery – The car struggles to start, or the battery keeps losing power.
Dim or Flickering Lights – Headlights and interior lights get dim or flicker, especially at idle.
Electrical Issues – Power windows, AC, or radio don’t work normally.
Strange Noises – Whining, grinding, or squealing sounds from the alternator area.
Burning Smell – Overheated alternator or slipping belt can cause a rubber or electrical odor.
Engine Problems – Stalling or rough idle due to low power supply.
Quick Test: With the engine running, check battery voltage. Normal is 13.5V–14.5V. Anything much lower suggests a bad alternator.
