Original GM Alternators

Factory GM alternators, also called generators, have a vital job. They deliver power to your vehicle's battery. They also send it to the rest of its electrical systems. A battery might start a car or truck, but the alternator keeps it running. When should you replace your alternator? That depends. One determinant here is how high-quality it is. A genuine, brand-new alternator is best, but a remanufactured generator can do the job just as well. Another is what conditions you drive in. It can even depend on what electronics you use. Both vary. However, an alternator can just plain fail without warning, too. Indicators of alternator failure include flickering headlights, electrical failure, and car radio unreliability. Both the alternator and battery can also smell burned. An alternator warning light can illuminate on the dash. Your engine can even start to squeal. You might not even see the signs of an alternator failure coming. For instance, you could jump-start your car incorrectly and cause one. Secondly, installing certain accessories could cause an overload. Alternator fluid could leak, or your alternator belt could be too tight, and both can damage its bearings. That means faster wear and tear. A failed alternator can even make electronics draw all their power from your battery. This can lead to a dead battery. Luckily, your local service center or mechanic can help. They'll do an inspection If your battery light's illuminated. They can run a charging system test if your headlights are dim. However, you'll know when to change your alternator if you check your owner's manual for its maintenance schedule.
