When the alternator on your car begins to fail, it’s important to get it checked as soon as possible.
The alternator is one of those mechanical components in your car that, although not complex, is vital to keeping your car running. The alternator creates an alternating current through rotating brushes. This current charges the battery in your car and powers its electrical components and systems. If it fails, the battery will not charge and your car won’t start. Clearly, it’s important to keep this hardworking component in good shape.
There are many things that can cause an alternator to fail. Fluid leaks or a tight belt can damage the bearings, causing the alternator to prematurely wear and die. Too many electronics in the car can also cause a drain on both the battery and the alternator. When your alternator goes, the battery cannot be charged and the car cannot run.
Identifying when your alternator needs to be replaced is not always easy, but there are a few signs and symptoms that you can look out for. One of the most common symptoms to look for is pulsating headlights or dashboard lights. If you’re driving at night and your headlights are going from dim to bright, this is a sign that it may be time to replace your alternator. Also, since the alternator is responsible for providing electricity, if the car radio or other electrical components are only working sporadically, this may also indicate a struggling alternator.
Of course, if your car doesn’t start at all or turns repeatedly before finally starting, this can also indicate that your alternator is wearing out. If your battery keeps dying, it may be a faulty alternator rather than a problem with the battery itself. A less common symptom is a burnt rubber smell usually caused by excessive heat building up on an alternator belt that isn’t able to move freely. A faulty alternator or belt might also cause a high pitched squeal. Keep an ear out for any grinding or whining noises as well as this could indicate a broken or worn out bearing.
All of your car’s electronics draw their power from the battery, so if the alternator is faulty this can drain the battery and cause it to die as well. Even though your battery light might be on, the problem may, in fact, be the alternator. So it’s important if the light is on or if you have any of the symptoms explained above that you get your alternator checked as well.
The alternator is an essential part of your car’s system. Don’t take a chance on it failing.
