Before the 1980s, cars used carburetors to supply fuel to the combustion chamber. Today, all cars use one of three fuel injection systems: direct fuel injection, ported fuel injection, or throttle body fuel injection.

Every car's electrical system is composed of a wiring harness that connects various computer, controllers, lights, actuators, motors and switches. This electrical system is intergraded throughout the car to communicate with each part using a central computer which runs the engine or main electric motor. The battery is responsible for supplying power to the car while the engine is not running but in electric cars the battery does all of the work while powering the motor. High amperage circuits are designed with larger components to handle the load without failing. Common maintenance includes inspecting electrical connectors that are visible including the battery cables.

When a lobe lifts one end of the rocker, the other end of the rocker presses down on the valve stem, opening the valve to let air in to the combustion chamber or letting exhaust out. It works sort of like a see-saw.

Components commonly connected to the wiring harness include the on-board diagnostic computer and fuel-injection system of many vehicles, auxiliary lights and dashboard controls. The emissions system and similar electrical components also connect directly to the harness, as do turn signals and other required systems. On many automobile wiring harnesses, the connectors and wires that connect these systems swap out easily for quick repairs and replacement.

These relay's act as electronic switches that are controlled by the computer or by a manual switch. Once engaged the relay connects a circuit which activates a particular device.

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.
