Automotive wiring
There is a lot of different automotive wiring in today's automobiles. This is despite the talk of changing over to fiber-optic networks. Even in General Motors latest multiplex systems they have chosen to go with electrical wire Instead of fiber optics. It appears that this future technology is still five to 10 years down the road. So let's discuss different types of wires. If you are looking for automotive wiring diagrams. You can go to my car repair manuals page for more information on where to find them. I also have a video on how to use them to fix common car electrical problems. Automotive wiring explainedThe solid strand wire or single-strand conductor like you would see in houses. And stranded wires that are made up of a number of small solid wires twisted together to form single conductors. Stranded wires are most commonly used in automobiles. Electronics such as computers use specially shielded twisted cable for protection from unwanted induced magnetic field voltages that can interfere with computer functions.
Its length and its thickness or gauge size determine the current carrying capacity and the amount of voltage drop in an electrical wire. Standardized wiring sizes were established by the Society of automotive engineers. AWG stands for American wire gauge. A numbering system ranging from zero to 20 with zero being the largest and the number 20 being the smallest thickness of wire identify sizes.
Auto electric wiring can also be classified as primary or secondary. The primary wiring carries low voltage to all of the electrical systems of the vehicle. The secondary wiring also called high-tension cable has extra thick insulation to carry high voltage from the ignition coil to the spark plugs. This insulation reduces the magnetic flux field created from the high voltage. When spark plug wires wear down the magnetic fields can effect other areas of the car. Sometimes the first system to be affected is the audio system. Ignition interference can often be heard through the speakers. Standard electrical wires
With all of this wiring running through the vehicle a way of organizing was necessary. Harness and it's connectors help divide the vehicles electrical system and provide a convenient starting point for tracking and testing many circuits. Many harness connectors are located in the dash or firewall area. As the number of electrical and electronic devices installed in today's vehicle increases so does the need for more wiring to support the devices.
Also when fiber optic networks are perfected this will reduce the vehicles weight along with the expensive copper wire. But until then we will have to learn how to use wiring diagrams along with standard electrical diagnosis procedures.
Do you have questions about automotive wiring and need answers now? Now that we have discussed wiring and the different sizes you can head on back to the main page for automotive electrical information. This next link takes you from automotive wiring to the auto electrical education page The most popular section of the you fix cars website is coming up on this next link. View some short but helpful automobile repair videos. You can search both of my automotive websites at the same time.  Custom Search The home page is available from this next link. It will tell you in more detail, what is available on this website, and more about the mechanic that built the. You can also find out why he believes.
