Once the wire problem is located, typically the damaged wire or two can be repaired, or a new piece of wire can be spliced in. But sometimes the damage is more extensive, wires are melted, or a hard-to-reach location makes repair impossible.

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.

If your vehicle has (or once had) a factory stereo, or if it was pre-wired with a "stereo prep" package, there should be at least one plastic wiring harness behind the stereo opening. This plug connects the stereo to your vehicle's electrical system and the speakers. You will need to unplug the factory stereo from the wiring harnesses, and unplug the antenna to complete the removal process.

It’s a thermo-setting plastic, which means it has a molecular structure that cross-links into very durable chains. And like other thermo-setting plastics, like polyurethanes, it remains pliable and resists oxidation and abrasion to a far greater degree.

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.

Once you have your fuse tap, the only tools you really need to connect the car radio to the fuse box are a wire crimper tool and a utility knife. If you are installing the radio in a classic vehicle, you'll need a Phillips screwdriver to connect the wire from the radio to the fuse box. Of course, you will also need a fuse rated with an amperage value rated for your car radio. You should be able to find the recommended amperage rating for the fuse in the radio installation guide. Most low-powered radios can use a 20-amp fuse without any issues. However, for high-powered stereos, those that produce 100 watts of power or more. You may have to use a 25- or 30-amp fuse. You may be able to use a wire clasp or harness already under the dash to secure the wiring from the radio to the fuse box. If there is no available clasp or harness, though, you can use some ordinary electrical tape to secure the new power wire for the radio to an existing wire bundles beneath the dashboard. The only other items you might need are a piece of 12-gauge electrical wire and a butt connector if the power wire from the radio is too short to reach the fuse box.

Like everything else in this world, there are varying degrees of wire quality. For years the standby wire insulation was Polyvinyl Chloride or PVC. Relatively tough, flexible, and inexpensive, it gets the job done, however, PVC is a thermoplastic. And like other thermoplastics like lacquers and synthetic enamels, it tends to oxidize and brittle with age.

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.

Since harnesses come in all sizes from small and simple, to large and complex, the cost to purchase and install them covers a very broad range. Some vehicle manufacturers also specify harness replacement, rather than wire repair, on certain sensitive safety systems such as airbags. This type of specific guidance varies between manufacturers and can be found in their service information.

The most foolproof way to check a fuse is to pull it out of its receptacle and hook up a continuity tester to both blades of the fuse. But if you do this while the fuse is plugged in, you could get continuity through a path other than the fuse (for instance, both sides of the wire may be grounded when you check the fuse).
