What Signs Indicate a Weak Alternator?

A vehicle’s alternator is an understated part of the electrical system in vehicles as the battery takes most of its credit. Even though your battery does contribute to starting the engine, it wouldn’t be able to run without the alternator. That is because the alternator is what charges your vehicle battery every time your car runs. Therefore, driving with a worn or faulty alternator can be dangerous. It can quickly lead to a dead battery and other electrical malfunctions. 


Below are some of the tell-tale signs that indicate a weak or broken alternator:

Dead Battery

The alternator turns mechanical energy from the engine's rotating pulleys into electrical energy to replenish the battery. When the alternator stops working, it won’t be able to properly charge your car battery. Eventually, it will run your battery flat.

Malfunctioning Electrical Accessories

Besides recharging the car battery, the alternator also plays a big role in powering an array of electrical devices and accessories throughout your car. These accessories include windshield wipers, headlights, power seats, power windows, and more. If you notice problems with any one or more of those functions, please bring your vehicle to the professional mechanics at Elite Auto Experts. While some of these malfunctions are more serious than others, you don’t want to deal with the inconvenience.

Battery Warning Light On

Dashboard warning lights are designed to signal trouble from within your vehicle. They are connected to a series of sensors and your onboard computer. If you notice a battery-shaped symbol or the letters ALT or GEN on your dash, there’s a good chance that your alternator is causing problems. It is vital for you to bring your vehicle to professional repair specialists to run tests on your electrical system.


A faulty alternator can quickly take the fun away from your time with friends and family and overall be a major inconvenience. If you suspect you need alternator repair, please bring your car to the experts at Elite Auto Experts today.
