Automotive Care: Alternators, Batteries, And Fuses
Your car's electrical system runs because of several essential components including: a battery, fuses, and an alternator. When any one of these components fail, your car won't run or it will perform poorly. Unfortunately, it isn't always apparent which part is giving you the trouble. We'll examine each component, discuss its unique characteristics, and outline simple maintenance options to help you make the proper diagnosis. 1. Alternators. Car alternator problems are usually noticed when you realize the juice to your headlights has been reduced. No longer can you see hundreds of feet in front of you, instead the light barely makes it past the front bumper. Check the wires leading to the alternator and make sure that they are secure and free of corrosion. Examine your alternator belt for cracks as well as for tension. If your headlights are still dim, then it is likely your alternator will have to be replaced. Don't put it off as the alternator can drain your battery. 2. Batteries. If your car won't start, your battery may be to blame. Most cars come equipped with sealed, maintenance free batteries. Still, "maintenance free" isn't an entirely correct designation as corrosion can build up on the terminals causing an otherwise fine working battery to fail. Remove the cables, clean with a wire brush, and reattach the cables.
