Alternators are small but essential parts of your car’s electrical system, charging the car’s battery when the engine is running. Therefore, it’s vital to know the warning signs of alternator problems so you can get them fixed before they cause your vehicle to stall. Here are five indicators that your alternator needs to be repaired or replaced immediately.
1) Grinding Sound
A failing alternator can cause a grinding noise while struggling to keep the engine running. This grinding noise is usually caused by bad bearings and is a telltale sign that your car’s alternator is failing. The alternator is responsible for providing a constant charge to the battery, so when it starts to fail, you’ll notice your car having trouble starting up, along with several other electrical problems.
2) Slow Engine Start
If your car takes longer to start up, it could signal that your alternator is going bad. On the other hand, when alternators fail, they often do so gradually. So if you notice that your engine is taking a little longer to start than it used to, it’s worth getting it checked out.
3) Low Power
If your car is having trouble keeping electrical components running, it could be a sign of a failing alternator. The alternator powers the electrical system in your vehicle, so if it’s not working correctly, it can cause dim lights or other electrical issues.
4) Active Check Engine Light
If your car’s check engine light is illuminated, that’s a warning sign that something is wrong with the vehicle. For example, it could be a sign of a failing alternator. The alternator is what charges the battery, so if it’s not working properly, the battery will eventually die. So if you see the check engine light, take your car to a mechanic to have it checked out.
5) Battery Dies Out Quickly After Recharging
One of the most common telltale signs of a failing alternator is if your car battery dies out quickly after being recharged. If your alternator is going bad, it’s not providing enough power to keep your battery charged, leading to all sorts of car trouble.
If you ignore the signs of a failing alternator, your car will eventually stall, and you will be unable to restart it. Get your vehicle to your trusted mechanic as soon as you suspect your car’s alternator is failing, and get your vehicle back to running worry-free.
