4 Signs of Alternator Failure that Should Be Addressed ASAP

Your vehicle’s alternator plays a critical role in keeping the electrical system running and the battery charged. When the alternator begins to fail, it can cause a wide range of issues that may start off minor but quickly become serious if ignored. At All Engines & Transmissions, we provide expert alternator replacement and auto electric repair in the greater Westminster, CO area. Here are four common signs that your alternator may be failing.
Dimming or Flickering Lights
One of the first signs of a failing alternator is dim or flickering headlights and interior lights. Since the alternator is responsible for generating the power needed to run your car’s electrical components, any inconsistency in its output can cause the lights to behave erratically. You may notice the headlights becoming dimmer while driving at night, which could pose a significant safety hazard..
Malfunctioning Electrical Accessories
If your alternator is no longer producing sufficient power, you may begin to notice problems with your vehicle’s electrical accessories. Power windows may move slowly, the radio might cut in and out, or the air conditioning system may stop working properly. These issues can be an early warning sign that the alternator is not supplying enough current to power all the systems in your vehicle.
Battery Warning Light on the Dashboard
Vehicles are often equipped with a battery-shaped warning light on the dashboard that illuminates when there’s a problem with the charging system. If the alternator is underperforming or failing, this light may turn on to alert you. It’s important to note that while the icon looks like a battery, it could actually indicate a broader charging issue, and the alternator is often the root cause.
Unusual Noises
A failing alternator can sometimes produce odd noises such as grinding or whining. These sounds may come from worn bearings inside the alternator or a misaligned belt. If you hear strange noises coming from the engine bay, it’s a good idea to have the alternator inspected as part of the diagnostic process.
