Notice that battery voltage travels through a high current wire (red) through the relay to the horn and also through a smaller wire (blue) through the ignition switch to the relay's low-current coil. The first thing you should be aware of is that the horn circuit is always "hot" or "live" when the ignition switch is turned on and all that's needed is a path to ground.

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.

Fuses are designed to fail when too much current is drawn through the device. This prevents heating of the wires and subsequent melting of the insulation, followed usually by fire!
By Hadrien Gratien. Car Electrical Wiring. Published at Wednesday, January 10th 2018, 01:32:49 AM. There are two types of electricity, alternating current (AC) and direct current (DC). When batteries discharge they emit a constant DC power in one direction, supplying electricity through the positive terminal to the negative. Most automotive components require this DC charge to work properly, but it is limited because batteries will eventually discharge completely, with no remaining power to give.

The engine harness is typically a large bundle of individual wires protected by a shell of insulation and conduit which helps to protect it from the elements. It is often asymmetrical, with the large end close to the fuse box and becoming smaller as it branches out over the engine. Since the various automobile manufacturers have different engine designs which also change over time, engine wiring harnesses are often unique to the year, make and model of a vehicle. Because of its proximity to the engine as well as contaminants on the road, engine wiring harnesses can degrade and require repair or replacement.

The battery supplies all of the power to keep the entire electrical system running, with the assistance of the alternator which ensures that the battery maintains its power. The initial portion of your engine wire harness carries electricity from the battery t the fuse box where it is further distributed.

By Salomon Herbert. Car Electrical Wiring. Published at Tuesday, January 09th 2018, 07:37:37 AM. 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.
