Like most seemingly complicated things, automotive electrical systems are collections of very simple assemblies. And lucky for us, there’s no secret as to how these things work. It boils down to basic technique. Do a few things right and you’re assured many trouble-free years of service.

While OEM and aftermarket wiring manufacturers alike combine multiple devices on single circuits, they take various things like current draw, wire gauge, and fuse capacity into consideration. For example, adding accessories to an existing circuit may require a greater-capacity fuse, which may cause problems if that fuse’s capacity exceeds the capacity of any single wire in that circuit. Should a wire find ground or its accessory fail in such a case, the wire may catch fire without ever blowing its circuit’s fuse.

A short circuit is what happens when a wire has rubbed through to ground causing a fuse to blow. An open circuit is what happens when a connection stops working because of a broken wire or a bad conductivity. Low battery voltage can cause strange problems to the electrical components of the car due to insufficient operating voltage. Because of the construction of wiring connectors they can sometimes create high resistance which causes heat making the connector have an open circuit. When performing wiring repairs a wiring schematic is sometimes necessary to trace wires or locate a component.

The other major issue within a car electrical system is that not all components tolerate the same amount of current strength or amperage. Therefore, the system must include voltage regulators and fuses to moderate flow and protect components that cannot handle the amperage supplied by the alternator. Fuses protect circuits when placed in front of the load (component). If a voltage spike causes too much amperage sent to the headlights, a fuse designed to “blow” at 15 amps will do so, preventing the current from continuing on to cook the headlight itself.

Inside the grooves piston rings are put in. The piston rings are the part that actually touch the walls of the cylinder. They are made from iron and come in two varieties: compression rings and oil rings. The compression rings are the top rings and they press outward on the walls of the cylinder to provide a strong seal for the combustion chamber. The oil ring is the bottom ring on a piston and it prevents oil from the crankcase from seeping into the combustion chamber. It also wipes excess oil down the cylinder walls and back into the crankcase.

Since electrons flow along the surface of a conductor and not through the conductor, a conductor of equivalent size with more and finer strands can carry more current.

Before you begin, start by setting the parking brake and removing the negative cable from the car battery to prevent accidentally short circuiting something. Your factory stereo will most often be mounted in one of the following ways: – secured in a metal mounting sleeve by spring clips – bolted to the dash with brackets – mounted to a rail system inside the dash
