Your car's alternator plays a crucial role in keeping the electrical system running smoothly. It’s responsible for charging the battery and powering various electrical components. As soon as you suspect that alternator trouble is brewing, you’ll want to alert the mechanic. Ignoring the symptom could result in your battery’s power reserve running dry, potentially leaving you stranded. At Hye-Tech Auto, we provide expert alternator replacement and auto electric repair in the greater Covina, CA area. Here are five warning signs of an alternator problem.

Dimming/Flickering Lights

One of the early warning signs of alternator failure is the dimming of headlights or flickering lights. The alternator supplies power to the lights, and if it's struggling, you may notice fluctuations in brightness. If you notice this symptom, it's important to address the problem promptly to avoid being left stranded with a dead battery.

Dashboard Warning Light

In many cases, the first indication of alternator trouble is an illuminated warning light, which should promptly be brought to the mechanic’s attention. Commonly, this light flashes on with the letters ALT or GEN or as a battery-shaped icon.

Strange Noises

Unusual noises coming from under the hood can be a sign of alternator trouble. A failing alternator may produce a grinding or whining noise, indicating potential issues with internal components such as bearings or the belt. 

Dead Battery

While a dead battery can be a sign of various issues, a malfunctioning alternator is a common cause. If your battery is consistently dying even after a jumpstart, it could very well be because the alternator isn’t charging it properly. 

Issues with Electrical Accessories

The alternator supplies power to electrical accessories such as power seats, power windows, and the radio. If it isn’t working right, then your car’s electrical accessories may start to malfunction.
