FAQ on Alternator Problems
A faulty alternator is one of the most common causes of headache for a car owner. Even though the alternator is a seemingly simple component of a car's inner workings, it serves a vital purpose. The alternator is responsible for essentially transforming mechanical energy from the engine into electrical energy that powers the car's accessories. It also keeps the battery charged.
Problems caused by a faulty alternator can range from minor (slow start, dim headlights) to major (dead car). The alternator is a central component that connects to and from other systems in the car, its functional status will affect a wide array of the vehicle's inner workings. There are a few common signs to watch out for when trying to diagnose an alternator issue. If you suspect your car's alternator may be faulty, ask yourself the following Frequently Asked Questions regarding alternator problems. It may be time to bring it in to the shop for a check up.
Q: What does it mean when my warning light turns on or my lights are dim?
A: Warning lights and dim lights are two major indicators that your alternator, while still somewhat functional, is on its way out. If you notice both of these things occurring, check your alternator yourself or bring it into your mechanic's shop. Catching it early and having it replaced or repaired will save you the hassle of dealing with a completely dead battery when you are running late for work.
Q: My car is exhibiting an unusual sight/sound/smell. Is this related to the alternator?
A: A faulty alternator can sometimes be discovered, especially by trained mechanics, by visually examining the belt. It can also sometimes cause the smell of burnt rubber and/or wires as well as a growling or hissing sound before the alternator goes dead.
Q: Is my dead battery because of a broken alternator?
A: Possibly. Nearly everybody is familiar with the dreaded "click" telltale sound when attempting to start the ignition that signals a dead battery. If you jump start your battery and are only met with a dead car again moments later, then it is a good sign that the alternator is broken.
Q: If my alternator needs repair, will I be able to tell from seeing loose connections under the hood?
A: Often times, a broken or loose connection in regards to the alternator is not visible except to a trained mechanic. If you do not see anything otherwise remiss under your car's hood, and yet suffer from a dead battery, for example, bring it into the shop. It may be a loose connection. The faint smell of hot wires may also signal a potentially broken connection.
