The alternator is a critical component of all internal combustion engines, as it is what keeps the engine battery charged. As you operate your vehicle, the alternator transforms the energy of the wheels turning into electrical power that goes into the battery, and that energy is later used to start the engine again. At Longview Alternator & Starter Co., we have extensive experience in providing alternators for trucks, tractors, and other equipment. In this article, we will go over a few ways to tell when your truck alternators are failing.
- Dimming Lights – One way to tell if truck alternators are failing is to pay attention to the brightness of the headlights. The alternator is supplying power to the battery, which in turn powers the headlights, so if your lights are flickering or dimming, then there is likely a problem with the alternator.
- Failing Electrical Systems – The headlights aren’t the only parts of your truck powered by electricity generated by the alternator. Other systems, such as the power steering and air conditioning, rely on that electricity as well. If any of these other electrical systems start to fail, we encourage you to stop by our shop—we offer a wide range of truck alternators, and we can find the replacement part you need.
- Low Battery – A third sign of failing truck alternators can be seen in the battery. If your truck battery frequently runs out of juice, then it means the alternator is not keeping it sufficiently charged, and the alternator must be replaced.
