Your vehicle’s alternator plays a crucial role in keeping your car running by generating electrical power and charging the battery while the engine is running. If the alternator fails, your car may experience a range of electrical issues or even stop working altogether. Recognizing the signs of alternator trouble early can help you avoid getting stranded. At Hye-Tech Auto, we provide expert alternator replacement and auto electric repair in the greater Covina area. Here are five signs of alternator trouble.

Dim or Flickering Lights

One of the most noticeable signs of alternator trouble is dim or flickering headlights and interior lights. Since the alternator powers your car’s electrical system, when it starts to fail, the power supply becomes inconsistent. This can cause your lights to appear weaker or to flicker.

Warning Light on the Dashboard

Many vehicles are equipped with a dashboard warning light that illuminates when there’s a problem with the alternator. This light usually appears as a battery icon, but it may also say ALT or GEN. If this light comes on, it’s a sign that your alternator isn’t generating enough electricity, and you should have it inspected as soon as possible.

Electrical Malfunctions

A malfunctioning alternator can cause a variety of electrical problems in your vehicle. You might notice that power windows, door locks, or your car’s radio aren’t functioning properly. These issues occur because the alternator isn’t providing enough power to run all the electrical systems in your car.

Dead Battery

A dead or frequently dying battery can sometimes indicate a problem with the alternator rather than the battery itself. If the alternator isn’t charging the battery properly while you drive, the battery will eventually lose its charge and won’t be able to start the car. If you find yourself needing to jump-start your vehicle often, it could mean that your alternator is not functioning properly and is failing to recharge the battery.

Strange Noises

A failing alternator may produce unusual noises, such as grinding or whining sounds. These noises can result from worn bearings or belt issues. If you hear these sounds coming from under the hood, it’s a good idea to have your vehicle inspected.
