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.

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.

This unit creates electrical power by utilizing a magnetized armature and outer copper windings which are connected to the battery using brushes. While in operation (engine running) this unit supplies electrical power for the vehicle while charging the battery at the same time.

A wire allowed to dangle on an exhaust manifold isn’t long for this earth. Dirt and vibration conspire to wear through wire fanned out on a floorboard. More than one amplifier screw has self-tapped its way through stray wires.

The solution is a set of diodes that serve as a kind of electrical check valve for current coming out of the alternator. Diodes only allow current to flow in one direction, so when AC goes in on one side, only DC comes out on the other.

Actually, every object has an electrical charge, but most are so small they are impossible to detect. To power something like a motor, we have developed man made chemical cells with high electric potential: batteries. Batteries in turn lend power to starting, charging and security systems, lights, ABS, computers, sensors, climate control and onboard accessories. They are probably the first thing you think of when you hear about electricity in automotive applications, but batteries are far from alone in running the system.

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.

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.
