Car Alternators and Car Batteries
Monday, June 21st, 2010The electrical system in a car operates everything from the engine starter and the accessories, to the gadgets and the on-board computer unit. Without car alternators, starter motors with car batteries, we would return back to the stone age where every car owner would need to manually jumpstart their vehicle. Magnetoelectric Machine provided spark to the plugs once the engine was operating in the first cars. That eventually developed to what is known as the self-charging electrical system which is basically a generator that delivers electrical charge to a battery.
It is a sophisticated system and not many drivers understand the concept of it when repairs are being explained by a car mechanic. Nevertheless, the self-charging electrical system remains synonymous in concept, and many of the more precious advancements are in the area of overall performance. Today, vehicle alternators keep charge in car batteries, as well as supply electricity for conveniences and the computers. Nonetheless, reliability remains an issue with the electrical components and replacing a battery or alternator are things one can anticipate over the course of owning a car.
Engines will keep running as long as they have source of electricity to provide spark. This is achieved by a 12-volt car battery, however, without an alternator to keep charge, the drain on the battery will be significant and the system will run out of juice in a short time. Conversely, an alternator provides ample electrical to run the systems, but the engine cannot start without power from a battery. For this reason, one should pay attention to certain electrical accessories for signs of a failing battery.
When car batteries become weak, it will show up in slow engine cranking, slower turn signals, dimmer headlights and even overheating. A battery is easily checked, and this should be done at the first signs of a diminished electrical supply. Since car alternators are important to the system, these should be regularly checked as well. A comprehensive check will determine whether the battery has simply outgrown its life span, or the alternator no longer has sufficient output to maintain a proper charge in the battery.
