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.

A power distribution center is used to route positive battery power throughout the vehicle using relays and fuses. This center is powered directly off of the positive post of the battery using a positive battery cable.

The fuse box takes power from the battery, which is in turn charged by the alternator, and protects the wires in the harness against surges that could damage sensitive components. The wiring harness provides a series of connections that allow experienced mechanics and vehicle owners to narrow down problems to specific systems and electrical connections, making it easier to work on the vehicle’s electronics.

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.

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.

The crankshaft is what converts the up and down motion of the pistons into a rotational motion that allows the car to move. The crankshaft typically fits lengthwise in the engine block near the bottom. It extends from one end of the engine block to the other. At the front of the end of the engine, the crankshaft connects to rubber belts which connect to the camshaft and delivers power to other parts of the car; at the back end of the engine, the camshaft connects to the drive train, which transfers power to the wheels. At each end of the crankshaft, you’ll find oil seals, or “O-rings,” which prevent oil from leaking out of the engine.
