By Gabin Placide. Engine Wiring. Publised at Tuesday, January 09th 2018, 15:52:07 PM. A wiring harness in the engine is a set of wires, connectors, and terminals which run all over the vehicle for relaying electric power and information. The harness plays an integral role in connecting a number of important components of a vehicle. The wiring harness is just like the central nervous and circulatory system of a human body which pass information and power throughout the body.

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.

The electrical system is a complex but essential part of what keeps your car starting, running, charging and doing the little, but important, things like locking the doors. And while voltage in automotive systems is much lower than say, household applications, it’s still important to enlist the guidance of a professional when making a diagnosis or beginning repairs because many components are extremely sensitive and can be easily damaged without proper training and knowledge.

If your vehicle has an upgraded version of the factory sound system (such as a Bose or Harman Kardon upgrade, for example) or an integrated stereo/climate control panel, you will probably need a special factory system wiring adapter in order to install a new stereo. An adapter allows you to use a new stereo with your existing speaker system.

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.

Make sure it is plugged in, free to move and not burnt or melted. Many of the electrical components on your vehicle can be tested without being removed by measuring a resistance value between certain contacts. If you’re handy with an ohm meter and have a repair manual for your vehicle you can test the component that way.

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.
