A small electromagnetic engagement coil consumes on the order of milliamps means just about any switch can activate it.

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.

These metal parts acts as a conductive connector for positive battery power completing the electrical circuit.

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.

Inside the PDC are many fuses and relays which protect and control the many electrical circuits such as fuel pump and fuel injection systems. Fuses are used to safeguard electrical circuits and are designed to pop stopping the voltage flow in the event of a power overload or short circuit protecting the circuit wire from burning.

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 timing chain holds the crankshaft and camshaft in the same relative position to each other at all times during the engine’s operation. If the camshaft and crankshaft become out of sync for whatever reason (the timing chain skips a gear cog, for example), the engine won’t work.
