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.

The engine harness is typically a large bundle of individual wires protected by a shell of insulation and conduit which helps to protect it from the elements. It is often asymmetrical, with the large end close to the fuse box and becoming smaller as it branches out over the engine. Since the various automobile manufacturers have different engine designs which also change over time, engine wiring harnesses are often unique to the year, make and model of a vehicle. Because of its proximity to the engine as well as contaminants on the road, engine wiring harnesses can degrade and require repair or replacement.

Relays are used in high power devices and are essentially electrically activated switches. When you turn your car on, multiple components turn on like the fuel pump, computer and electric fans. A small amount of power is run through the switch in your ignition which can then activate multiple relays turning all the peripheral equipment without running full power for all of them through the ignition switch. Relays also can go bad over time and cause electrical problems. The best way to test a relay is to have a helper touch or listen to the relay while you turn the device on. You should feel a slight tap and hear a quiet click as the relay engages.

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.

The high amps produced by a car battery can provide quite an electrical shock if you get careless while wiring your car stereo to the fuse box. Therefore, before you get started, pop the hood on your vehicle and disconnect the negative battery terminal cable, the black one. This precaution will prevent you from being shocked while working with the wiring. Just to be sure, switch off the ignition and remove the key as well.
