If your battery light comes on or flickers on your dashboard, it could be a sign of an alternator going bad.
The alternator is driven by the engine to produce electricity to run the accessories in a vehicle and recharge the battery.
Some common problems that could lead to an alternator not working correctly can be normal wear and tear, and the brushes or diodes going bad. A common overlooked problem is a drive belt — or serpentine belt — becoming loose or stretched and slipping around the alternator.
The large number of electronics in today’s vehicles and all the accessories drivers like to plug in puts a heavy load on the alternator. The alternators actually have to be more heavy duty than before so they can charge the battery at a consistent rate.
The battery light coming on steady or flickering, especially when you come to a stop, are some signs that you’re having an alternator problem.
If you’re having a problem starting your car, it could be because the alternator is struggling to charge the battery.
If you believe you’re having any problems, you’ll want to have your vehicle checked with good electrical diagnostic equipment at your local auto repair shop. Because of the demand on the electrical system and the way alternators are designed, the old way of checking alternators isn’t always accurate.
