Yours Cars Electrical System of circuits?
When the automotive industry was in its infancy, it used electricity only to ignite the fuel inside the engine. By the late 1920's, the electric starter replaced the hand crank, electric headlights made acetylene lamps obsolete and the braying of the electric horn drowned out the squeak of the hand-squeezed air horn. Today, an automobile requires an elaborate electrical system of circuits just to produce, stores, and distribute all the electricity it requires simply for everyday operation. The first major component in the electrical system is the battery. The battery is used to store power for starting, and for running auxiliary devices such as clocks, radios and alarms when the engine is off. The next major component is the starter motor, which is used to start the engine. The third component is a charging device powered by the engine, known as the alternator. It powers the electrical system when the car is running, and restores the charge within the battery. With these basic components, the car maintains its supply of electricity. A device called the voltage regulator keeps the power level stabilized, and the fuse box keeps minor problems from becoming major ones. • Blown fuse: Is one part of the electrical system not working like the interior lights or dash lights? The first thing to check is the fuse. Look for the fuse panel under the dash, in the glove box, or even in the engine compartment in some cars. Circuit will label most fuse boxes. Modern cars use a blade type fuse, which is rectangular in shape and transparent. Look for the wire, which runs through the fuse, and see if it is burned through. Any discoloring of the fuse is a good sign the fuse has blown. If you have doubts, replace with a new fuse and test the system, which is not working. • Alternator: Does your car start ok, but your headlights dim when idling. It could be a bad alternator. When the alternator cannot produce enough electricity to keep the electrical systems running and the battery will have to be used to take up the slack. This will eventually wear down the battery and not allow your car to start. o Battery could not have enough power stored in it to spin the engine. A bad cell in the battery or from a bad alternator not charging the battery when the engine is running can cause this. If you can get the car to a mechanic, have him or her test the battery and charging system with a special tester. This tester places a load on the battery and can tell the condition. They can also check to see if the alternator is working to it's full potential. • Clean your battery connections at least once a year. Parts stores sell a handy terminal cleaner which is basically a round wire brush, which works wonders. Once you reattach the terminals, coat with a layer of heavy grease or special purpose grease sold at parts stores. This layer will block the air from reacting with the connectors and creating corrosion. That's it... turn the key on the dead car and the car should start. If it does not, try revving the engine on the good car to boost the charge coming from the alternator. If this does not work, try wiggling the cables to assure you have a good connection. GOOD sets of jumper cables are a necessity. I have had cheaper sets not jump-start a dead car. I actually had to double up two cheap sets to get enough current to start my car. The cheaper sets will have thinner cables, which cannot carry enough amperage to start some stalled cars. I would suggest buying a cable, which has 4,6 or 8-gauge wire.
