5 Symptoms of Alternator Trouble

Bay Brothers Automotive • Aug 04, 2024

When you first notice a sign of alternator trouble, it’s best to alert the mechanic. Otherwise, the issue could soon get worse and end up leaving you stranded. At Bay Brothers Automotive, we provide expert alternator replacement and auto electric repair in the greater Tampa area. Here’s a look at five indications of an alternator problem.


Dim or Flickering Lights

If your headlights seem unusually dim or flicker while you are driving, it could indicate that your alternator is not providing enough power to keep them fully lit. This symptom can also extend to your interior lights, causing them to flicker or dim as well.


Weak/Dead Battery

A weak or dead battery is another common sign of alternator trouble. The alternator is responsible for charging the battery while the car is running, so if it is not functioning properly, the battery will not receive the charge it needs to stay powered. 


Strange Noises

Unusual noises coming from your engine can also be a sign of an alternator issue. These noises might include a grinding or whining sound. The grinding noise can result from worn-out bearings inside the alternator, while a whining noise can be caused by a misaligned or slipping serpentine belt that connects to the alternator. If you hear these noises, it’s important to have your vehicle inspected to determine the exact cause.


Electrical Accessory Malfunctions

Another sign of an alternator problem is electrical malfunctions in your vehicle. Since the alternator powers many of your car’s electrical systems, issues like malfunctioning power windows or a malfunctioning radio can be traced back to a faulty alternator. 


Warning Light on the Dashboard

Modern vehicles commonly feature a warning light on the dashboard that indicates a problem with the charging system, often labeled as ALT or GEN. If this light comes on while you are driving, it is a clear sign that there is an issue with your alternator. Ignoring this warning may lead to more severe electrical problems and eventually leave you stranded, so it is crucial to have the alternator checked as soon as the light appears.
