The work of an Automotive Service Technician also known as a Mechanic has changed from normal mechanical repair to a high knowledge and very technical job. Today, integrated electronic systems and complex computers run and maintain vehicles. They also measure their performance while on the road and can adjust to certain conditions. Technicians must have a good base of knowledge about how vehicles components work and interact, as well as the capability to work with electronic diagnostic equipment and computer based vehicles. The most important system of your vehicle would definitely be the electrical system; the electrical system maintains almost everything in you car; from climate control to just adjusting your seat. There are many components to an electrical circuit that many people don’t know of. There are tons of different switching devices, protection devices, moving devices and plain old ingenious devices that seem to not even be possible. The car industry has really turned to upgrading there vehicles with more electrical devices to make the driver more comfortable when operating this brilliant machine. The most updated electrical device on a vehicle that I can think of is the Tire Pressure Monitoring System (TPMS), which actually measures a wireless sensor that is installed in your tire to let you know if your tire pressures are off. The first thing that I would like to do is explain what electricity is in an automobile. Electricity is the worlds most widely used source if energy. Electricity is the flow of electrons through a conductor to eventually be used to supply a load of some sort. The electrons flow from positive to negative. In order to understand how an electric charge moves from one atom to another, you need to learn a little about atoms. Everything that surrounds us is made of atoms; every piece of grass, every plant, every animal. The human body is made up of a great amount of atoms. Air and water are made if
