5 Indications of Alternator Failure that You Shouldn’t Ignore

Your vehicle’s alternator is a key component of its electrical system, responsible for keeping the battery charged and ensuring that various electrical components run smoothly. When the alternator starts to fail, it can lead to a range of issues that may even leave you stranded. At Hage-Kobany Transmissions & Auto Service, we provide expert alternator replacement and auto electric repair in the greater Columbia Heights, MN area. Here are five common signs of alternator trouble.
Dim or Flickering Lights
A common symptom of alternator trouble is dim or flickering headlights, dashboard lights, or interior lights. Since the alternator supplies power to your car’s electrical system, when it starts to fail, it can't provide consistent electricity. This can cause your lights to flicker or appear dimmer than usual.
Weak or Dead Battery
If your car’s battery keeps dying, it could be a sign that the alternator is no longer charging it properly. While batteries do have a limited lifespan, if you find yourself frequently jump-starting your vehicle, the underlying issue may be the alternator. A failing alternator won’t recharge the battery while you drive, leaving it drained.
Strange Noises
Odd sounds can also indicate alternator issues. A failing alternator may produce a grinding or whining noise due to worn-out bearings or belt issues. If you hear such noises, it’s a good idea to have your alternator inspected before the situation worsens.
Malfunctioning Electrical Accessories
A bad alternator can cause your car's electrical system to act erratically. You might experience power windows or seat adjustments slowing down, the radio cutting out, or other electrical accessories malfunctioning. This is because the alternator isn't providing sufficient power to operate everything correctly.
Warning Light on the Dashboard
Most vehicles have a dashboard warning light that illuminates when there's an issue with the charging system. It might look like a battery symbol or read ALT or GEN, depending on the vehicle model. If this light comes on, it’s a potential sign that your alternator is failing or struggling to supply power.
