While OEM and aftermarket wiring manufacturers alike combine multiple devices on single circuits, they take various things like current draw, wire gauge, and fuse capacity into consideration. For example, adding accessories to an existing circuit may require a greater-capacity fuse, which may cause problems if that fuse’s capacity exceeds the capacity of any single wire in that circuit. Should a wire find ground or its accessory fail in such a case, the wire may catch fire without ever blowing its circuit’s fuse.

Fusible Links, another kind of fuse, are used in many cars and are almost always found in the wiring harness in the engine compartment. These are molded, single-purpose links in the wire which are designed to melt under extreme conditions (usually a crash which might crush wires together, causing a huge short circuit). Your car's schematic will show their use and location.

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.

When you replace that radio, these warning sounds are lost, and that's dangerous. Thus, these vehicles require a special harness to keep these audible tones working when you install a new stereo. Fortunately, these harnesses also take care of all of the basic stereo connections.

When fuel ignites in the combustion chamber, the force pushes the piston downward, which in turn moves the crankshaft (see below). The piston attaches to the crankshaft via a connecting rod, aka the con rod. It connects to the connecting rod via a piston pin, and the connecting rod connects to the crankshaft via a connecting rod bearing.

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.

An electronic throttle control actuator is responsible for metering air flow into the engine which controls engine speed. A throttle control sensor located near the foot pedal supplies feedback data to the computer which activates the actuator. The throttle control system is integrated into the ABS, cruise control and traction control systems. In older vehicles throttle action was performed by a manually controlled throttle cable which is actuated by the driver's right foot.
