What is an Alternator?

The alternator is responsible for two things. First, it powers the electrical units when your car is running. The radio, lights, window switches, USB ports, etc., are all powered by the alternator. And second, it recharges the car’s battery, which is the source of electricity when the car is turned off. Your car’s alternator gains power from the engine. It’s connected to the engine via a drive belt, and it converts that energy into usable electricity. It’s a pretty simple system. However, the alternator does need to be regulated, to make sure that nothing is overcharged or undercharged. In older cars, that’s the job of the voltage regulator. In newer cars, the engine control module (ECM) is responsible for those duties.

Symptoms of a failing Alternator

Car won’t start

When your car is running, the alternator uses energy from the engine to recharge the battery. When the car is off, it needs that electricity from the battery in order to turn back on. If the car won’t turn on, it may be because the alternator isn’t recharging the battery.

Hard starting

Similarly, if the alternator isn’t charging the battery sufficiently, you’ll likely have trouble starting the car, also known as a hard start.


You might think that these issues only arise when starting the vehicle, but a malfunctioning alternator can actually result in stalling when your car is turned on.

Lights that are too bright or too dim

If the alternator is sending too much electricity to the electrical units, your car’s lights will likely be brighter than they’re supposed to be. Conversely, if the alternator isn’t sending enough electricity, then the lights will be too dim.

Whining noise

A busted alternator will often make an annoying whining noise when the engine is running.

Warning lights

A malfunctioning alternator will usually result in a warning light or two illuminating on your dashboard. The check engine warning light and a charging system warning light are most common.

How urgent is an Alternator replacement?

Usually a faulty alternator won’t cause further damage to the vehicle. However, if it is overcharging or undercharging certain electrical units, it is possible for some damage to occur. A malfunctioning alternator does make your car less reliable, however, due to the potential issues with stalling and starting, so it’s best to get it replaced immediately if you’re starting to notice the above symptoms.
