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.

Before performing any work on your vehicle always be sure to disconnect and ideally, remove the battery from the vehicle. You should be able to take off the negative, then positive terminal clamps with a socket wrench, and then set the battery somewhere cool, out of the sun, and away from your work space.

The primary source of this electricity is the vehicle's battery. When the engine is running, the battery is charged by a part of the engine called the alternator. Before it is distributed, the electricity travels through the fuse box, where fuses on each circuit prevent components from receiving too much power in the event of an electrical disturbance. Different wiring harnesses then distribute the electricity to the engine and throughout the vehicle.

Inside the PDC are many fuses and relays which protect and control the many electrical circuits such as fuel pump and fuel injection systems. Fuses are used to safeguard electrical circuits and are designed to pop stopping the voltage flow in the event of a power overload or short circuit protecting the circuit wire from burning.

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 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.

If a harness is not available for your vehicle or if the factory stereo plug was cut off, you'll need to identify each of the car's stereo wires and connect them to the corresponding wires of your new stereo.

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.

You may be lucky and just have a loose wire and banging just right on something might get it to fall back into place, but most times electrical problems are not that simple. Vehicles built in the 60s and 70s had very few electrically controlled devices as most things were controlled through a mechanical linkage. In the 80s and early 90s many automobile manufacturers started using vacuum controlled solenoids to operate small things like switches in the engine or the vents on your ventilation system. Since then, just about everything has become electronically controlled and regulated. Most of the electronics in your vehicle will last a very long time and never be changed, but when something does go wrong it can be difficult to pinpoint the problem.
