If your automobile’s interior and exterior lights are flickering, the alternator is no longer able to produce a steady stream of electricity. Generally, the alternator produces between 13 volts and 14.5 volts to power numerous accessories and components found in your car, truck, or utility vehicle. Central Auto Care advises you can get about 10 years out of the factory alternator. After this time, you may start having problems with your vehicle’s lights or one or more of the problems listed below.
Dead Battery
Aside from light problems, you may also find that your battery is dying constantly. If the battery itself is not too old, the problem is most likely that the alternator is no longer keeping it charged. This is just one of the things that the alternator does. You can tell that the problem is the alternator if the battery does not retain a charge after it has been jump-started.
Frequent Stalling
Your engine may also start to misfire and stall frequently if the alternator is going bad. This is a sign that the alternator is not producing enough power to keep the spark plugs firing in sequence. Consequently, they will misfire and cause your engine to shut down.
Hot Electricity
We listed a maximum voltage of 14.5 volts above. Sometimes, when the alternator malfunctions, it actually produces more voltage than this. When this happens, you run the risk of an electrical fire starting in your engine because it will overheat the electrical system.
Slow Accessories
We also mentioned above that the alternator provides power to your automobile’s accessories. This includes things such as the power seats and windows, the USB charging ports, and the navigation system. If the alternator is having problems producing power, you will start to have problems with your vehicle’s accessories. They will slow down or shut off by themselves.
Strange Noises
Sometimes, the alternator will give you a warning that it is wearing out. As the internal mechanisms wear down, the alternator will start to make grinding or growling sounds. The alternator also has a belt that helps it produce power. When it is having problems, it makes squealing or whining sounds.
Warning Light
Finally, you may end up with the dashboard warning light turned on by the engine control unit because the alternator has reported an error. In newer automobiles, this light is the battery light. If you drive a vehicle that is a few decades old, you will see an ALT/GEN light.
