For car owners, a dead battery or a faulty alternator is a rite of passage. It might happen at the most inconvenient of times, but it’s a minor problem that we all encounter at least once or twice. If it’s been more than a few years since you’ve had the battery replaced, it’s a good bet that it’s time to replace it, and an auto technician can determine a faulty battery with a simple test. The alternator is a component inside your electrical system that keeps your battery charged properly, and a faulty one means that the battery isn’t getting the charge it needs to run.
The good news for car owners, however, is that figuring out if you have an alternator that’s going bad before an inconvenience is simple if you know what to look for.
If you notice any of these symptoms, seek the help of your auto technician—the sooner, the better. Being preemptive about car care can be the difference between catching issues before they become issues, and being stranded with a car that won’t start.
