Your Cars Electrical System
by: Kevin Schappell
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, store, 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.
Many different auxiliary electrical devices are used in modern cars, such as: radios, cellular phones, rear window defrosters and electric door locks, as well as a vast array of motors powering everything from the moon roof on down.

Common Problems:
Troubleshooting:
I don't think there is a tougher system to troubleshoot on your car than the charging/starting system. This is due to the fact that there are many things that can go wrong and it's tough to test some components without special equipment. Let's go over some possible situations and their possible causes.
As you can see there are plenty of things to go wrong with the charging system and it is always best to take the car to your mechanic and have it tested before you go replacing parts blindly.
Preventing problems with your electrical system:
How to jump start your car:
Jump-starting your car does not have to be a hard task. First lay out the cables on the ground between the two cars. Make sure that the cable is not tangled and none of the end clamps are touching each other. The car with the good battery should be running.
Step 1: Take the positive (red) clamp closest to the car with the good battery and hook it to the positive terminal of that car. The positive terminal will have a + sign on it and usually a red wire running to it.
Step 2: Repeat this step on the car with the bad battery, hooking up the positive clamp to the positive terminal on the battery. Make sure the clamps are contacting well and can not fall off.
Step 3: Take the negative cable (black) closest to the car with the good battery and hook it to the negative terminal of the battery. The negative terminal will have a - sign and usually a black wire running to it.
Step 4: This is the last step and the most important. Take the negative clamp closest to the car with the bad battery and attach it to a bare metal part of the engine. DO NOT hook it to the batteries negative terminal as there maybe hydrogen gas present from the battery and a spark from the connection could cause an explosion.
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.

Winterizing Tips for your Lawn and Garden Your outdoor plants have worked hard for you all summer, making your yard a place you’re proud to call home. Properly winterizing your lawn and garden is an important step toward healthy soil, lush grass, and happy plants next year. Remember to take care of your outdoor accessories, including your lawn equipment, gardening tools, and all of your lawn and garden decor. A little time spent this autumn will make your gardening and landscaping efforts easier and more enjoyable next spring! Let’s start with the easy jobs - First remember to store all of your lawn and garden decor including fragile planters, gazing balls, and your deck furniture. Unglazed terra cotta planters left filled with soil outside will often break in the freezing temperatures so it is best to clean them and place them in a storage area where they are protected from the elements. Autumn is the time to find your birdfeeders and to start stocking your winter feeding pantry. Soon your many feathered friends will be flocking to your feeders for that nutritious morsel. Remember to keep your feeders full through the winter as the birds need reliable food sources through the winter months. Now that you’ve done the easy tasks, let’s move on to the more mundane winterizing chores. Start by simply cleaning up the vegetable garden. After the first hard frost, remove the year’s annual plants and the dead vegetation. You can add this material to your compost pile, but make sure you’re not adding material from diseased or pest-infested plants. You’ll want to pull perennial weeds before you mulch your garden down for the winter. The best part of fall landscape chores is planting the spring-blooming bulbs. Crocus, tulips, and daffodils are a beautiful addition to the early spring landscape. In the yard there’s the major job of raking leaves. These are great either in the compost pile or as direct mulch on the garden. Perennial flowers may be smothered by a heavy layer of mulch, however. Also, wait to prune your trees until later in the winter. After the ground freezes you can mulch your perennial flowers and newly planted trees. Certain shrubs will need to be wrapped in burlap to protect them from wind damage, sun scald, and other winter injury. Moving on to the mechanical tasks of winterizing your lawn and garden - While you might try to procrastinate on these jobs until spring, you’ll be well rewarded for the maintenance you perform this fall. Drain the gas from your lawnmower and string trimmer. Actually it’s best to let your mowers and trimmers simply run out of fuel. If you don’t want to ‘waste’ that little bit of fuel, add a gas conditioner before the long winter. Be sure to follow directions. Also, take the same care with your gardening equipment such as your rotary tiller. Clean all of your landscaping equipment before you store it away for the long, cold winter. Wash with soap and water, clean the air filter, and change the oil. You’ll find that first lawn mowing job in the spring a little bit easier if you take time to sharpen the blades now. You can protect that freshly sharpened blade by applying a little spray oil to the blades. You can also apply light spray oil to other moving parts such as cables and the throttle controls. Lastly, drain all of the water from the garden hoses and turn off the taps. Be sure to store your insecticides, herbicides, and fertilizers in a safe storage area that will not freeze. Make sure these materials are kept away from children and pets!
