What Makes Up An Electrical System in a Modern Car?

What are the components of your car's electrical system, and how does your car's electrical system work?   From How Cars Work:
"The electrical system of a car is a closed circuit with an independent power source the battery. It operates on a small fraction of the power of a household circuit. Current flows along a single cable from the battery to the component being powered, and back to the battery through the car's metal body. The body is connected to the earth terminal of the battery by a thick cable. This type of circuit is called an earth-return system any part of it connected to the car body is said to be earthed.
The strength of the current is measured in amperes (amps); the pressure that drives it round the circuit is called voltage (volts). Modern cars have a 12 volt battery. Its capacity is measured in amp/hours. A 56 amp/hour battery should be able to deliver a current of 1 amp for 56 hours, or 2 amps for 28 hours. If the battery voltage drops, less current flows, and eventually there is not enough to make the components work." [READ SOURCE ARTICLE]
So remember, that you want to make sure that your battery is in good condition, particularly in Arizona's extreme environment.   Your car battery can literally have the moisture baked out of it, which causes batteries to have a much lower life cycle than batteries in other parts of the US.    As a rule, you have to replace your battery every three years in Arizona.  However, your battery is only one part of your electrical system.  You also have to deal with your alternator as well.

Your Alternator:  Three Strikes

One auto electrical problem you may encounter is only partially connected to your battery.  A lot of times, your alternator can mimic a battery problem.  Sometimes, the way that you can tell is that your alternator will go bad after three or four battery replacements.  Your auto's electrical system is complex.  It could be something as simple as a bad wire, or it could be something more.
Whatever the problem is in your electrical system, unless you know what you are doing, make sure you take your car in if it is acting up.  Your best bet is to get to an auto repair shop in Phoenix.
