For example we can determine if an ignition coil is healthy or not by measuring the resistance of its windings. To measure resistance, set your meter to Ω ohms resistance. If you need to select a range, select the smallest range normally 200 ohms. Place the red probe onto one of the small terminals of the ignition coil, and the black one on the remaining small terminal. Your resistance will then display. A normal ignition coil should read about 3.5 to 4 ohms. If your meter reads a much higher resistance it means your ignition coil may have a short and is faulty.

Electrical symbols are used on home electrical wiring plans in order to show the location, control point(s), and type of electrical devices required at those locations. These symbols, which are drawn on top of the floor plan, show lighting outlets, receptacle outlets, special purpose outlets, fan outlets and switches.

Once you do, you are able to read diagrams quickly, and can often understand a circuit at a glance. The more you work with both line and wiring diagrams, the better you will become in analyzing them.

Modern electrical machine tool equipment may vary from that of a single-motor machine (such as a drill press that performs simple, repetitive operations) to very large, multimotored automatic machines, which contain highly complex electrical control systems. Typically, these machines are especially designed, factory-wired, tested by the builder and then erected in the plant.

The continuity function measures resistance, and if there is a complete connection the meter will give an audible beep. If there is no continuity your DMM will show “OL” on the display meaning there is an open line. You can use this to test for electrical shorts in wiring or components. I commonly use this function to quickly test for shorted ignition switches and ignition coils.

When electricity was originally used for practical purposes, it was used for communication in the form of the electric telegraph and the telephone. Petroleum and paraffin lamps were still lighting homes until the late 1800s, when Thomas Edison developed the light bulb.

You must totally enclose conductors and their connection external to the control panel enclosure in suitable raceways or enclosures. Unless used for flexible connections involving small or infrequent movements, or connections to normally stationary motors, limit switches and other externally mounted devices, fittings used with raceways or multiconductor cables must be liquidtight.
