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.

Cars now have literally thousands of circuits. In this article, we'll go through some of the key components in your car's wiring, starting with the wire itself. Then we'll discuss fuses and connectors and see how it all fits together.

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 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.

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.

Now you have isolated the problem to the relay and only two things can be wrong: either the relay's coil isn't energizing (due to an internal broken wire) or the high-current contacts are being drawn together but no current is passing through (remember high-resistance connections?). If the coil is bad the relay must be replaced. If the contacts are charred, file them smooth.

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.
