The alternator is a vital part of your car. Without it, the battery power alone would not keep your car running. The alternator in your Infiniti is what supplies power to a range of systems in the vehicle as well, ranging from the headlights to the radio. Generally, alternators need replacement when some issues are noticed, such as dim headlights or dashboard lights. Any drop in performance of electrical components such as these might be slight and increase over time. If you know your battery is in good condition but it keeps dying, this could point to an alternator problem as well. If the battery doesn't get enough power, you might find you are having difficulty starting the car. This can all be attributed to a faulty alternator. If you find you need to replace your alternator, it's important to get a high quality replacement. Opting for an OEM alternator ensures that it will be good quality and fit your Infiniti.
