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.

Most high-performing cars (Jaguars, Maseratis, etc.) have four valves per cylinder (two intake, two outtake). While not considered a “high performance” brand, Honda also uses four valves per cylinder on their vehicles. There are even engines with three valves per cylinder — two inlet valves, one outtake valve. Multi-valve systems allow the car to “breathe” better, which in turn improves engine performance.

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 power distribution center is used to route positive battery power throughout the vehicle using relays and fuses. This center is powered directly off of the positive post of the battery using a positive battery cable.

Alternators are actually small generators capable of turning mechanical into electrical energy. Driven by the engine belt, alternators use a small signal from the battery to energize a field current that turns a rotor inside a set of stators. Since this energy is driven by the polarity of magnetic fields, the current produced as a result changes direction as the rotor turns, producing current in opposite or alternating directions (hence AC). Alternators produce significantly higher currents than initially supplied by the battery, so they are used to recharge the battery itself and power other electrical components.

The pins and sockets are responsible for conducting electricity from one half of the connector to the other. These are made very precisely so that the pins and sockets fit together with just enough force to ensure a good connection, but not enough force to make connecting and disconnecting too difficult.

There are small, rounded indentations cast into the cylinder head in order to create room at the top of the chamber for combustion. A head gasket seals the joint between the cylinder head and cylinder block. Intake and outtake valves, spark plugs, and fuel injectors (these parts are explained later) are also mounted to the cylinder head.
By Mathis Camille. Car Electrical Wiring. Published at Saturday, January 13th 2018, 20:30:12 PM. The most common problems with electrical systems are a short or open circuit. 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.
