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.

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 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.

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.

Harnesses are wrapped in a protective covering and then routed and secured throughout the vehicle to protect them from damage. But life for vehicles can get tough. Constant vibration, flexing, exposure to heat and cold, water, ice, and salt can all eventually take a toll on the wiring. Wiring harness damage is also not unusual when a vehicle has been involved in a collision.
By Jeannot Ludovic. Car Electrical Wiring. Published at Friday, March 09th 2018, 23:52:25 PM. The most common problems with electrical systems are a short or open circuit. 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.
