To ensure that your vehicle starts up and stays running, it requires a significant amount of battery power. As such, your battery needs to have an energy reserve for it to keep your car running in optimum condition. The alternator works toward keeping this power reserve replenished. Keep in mind that your vehicle's power supply is not simply for enabling your car from moving from one point to another. This power also works toward keeping your car's lights on, the car radio working, power windows opening and closing and many other applications. In the event that you require alternator repair, it is best to have the issues established and addressed as soon as possible so as to avoid any inconveniences down the road. But even before that, it is good to be able to notice there is a problem; here are some of the different signs indicating that you may require alternator repairs.
Your vehicle's lights light up erratically
Generally, once your put on the lights in your vehicle, be it the dashboard lights, the interior light or the headlights, they will have a steady beam. If your alternator is facing impeding damage, you will find that these lights will begin to act erratically. The most common problems with the lights would be constantly dimming. This can impair your vision on the roads and will also impede your ability to view your dashboard while driving in the dark. However, a faulty alternator can also cause the lights to shine brightly in an erratic manner too. If you notice the light inside and outside your vehicle have started acting strange, it is recommended to have an auto mechanic check your alternator out.
Your battery is constantly weak
Another sign that you should not ignore when it comes to alternator problems is a weakened battery. Granted, if your car battery is old, then it could simply mean it is on its last legs. However, if the battery is either fairly new or reasonably aged, then it could be a sign that it is not receiving enough reserve power from your alternator. Keep in mind that a car battery can only be charged to a certain extent. When the car is in use, the alternator is supposed to work toward replenishing the energy so that the battery does not die on you. If it is not receiving a sufficient amount of power, then chances are there is an underlying problem with the alternator and it should be addressed before it causes permanent damage to your vehicle's battery.
