4 Common Symptoms of a Failing Alternator

4 Common Symptoms of a Failing AlternatorCars use a lot of electricity in order to start and continue running, as well as to power all of their systems and accessories. Where does that electricity come from? The alternator. The alternator utilizes the motion of the motor to create electricity to keep you on the road. As the miles roll up on the odometer, as with most parts of a car, the alternator can begin to malfunction or fail completely. If you notice any of the following symptoms of alternator trouble it would be wise to head to the auto shop, before you end up with a car that won't run at all.

Dim/Flickering Lights

The alternator is tasked with providing the electricity that operates the lights as the engine is running. If your vehicle's headlights or dash lights are noticeably dimmer or flickering, there's a good chance the alternator is on its way out. If you think this may be the case, rev your engine with the lights on; if they get brighter when you rev, it's almost certainly an alternator issue.

Electrical Issues with Accessories

It's possible that you will begin to have issues operating electrical accessories such as power seats or windows. You may not be able to utilize interior lights or the radio could even shut itself off if the alternator is unable to produce the power necessary to operate it.

Engine Stalling or Rough Idle

Since fuel injection systems require a large amount of electricity to operate, there's a good chance the engine itself will have a hard time idling or even shut off while driving, since gas won't be able to flow into the combustion chamber.

Dead Battery

A telltale sign of a failing alternator is a repeatedly dead battery. While you may jump start the car the first time it happens, thinking maybe a light was left on or something, if the battery continuously dies, it is most likely because the alternator is no longer able to recharge it.

Additionally, the car will likely trigger a dashboard indicator light if the alternator is failing. It usually will read ALT or GEN, but it could be your car's check engine light that comes on, depending on the model, so don't delay diagnostics..
