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.

A highly disturbing device (variable speed drive, frequency converter, etc.) will have less radiation in the panel if it is “encapsulated” in a small, electromagnetically sealed, unpainted metal enclosure.

No click of the solenoid, nothing happens at all. Before assuming your starter is bad, grab your DMM and set it to DC Volts. Remove the wire going to the small terminal of your starter solenoid and connect the red probe of your DMM to the wire. Now connect your black probe to a ground. Turn your tractor’s key. Your DMM reads no voltage. This tells you that power is not going from your battery to the solenoid. Next remove the wires from the back of your ignition switch that are connected to the “B” and “S” terminals on your switch. Set your DMM to Continuity and connect your probes to the “B” and “S” terminals of the switch. Turn your tractor’s key and if there is no “beep” you know your ignition switch has a short internally and should be replaced.

Wires and cables (conductors) are insulated and protected by a variety of materials (insulators) each one having its own particular properties. The type of material used will be determined by the designer who will take into account the environment in which a control panel or installation is expected to operate as well as the application of individual wires within the panel.

This is essential for industrial control systems that may contain hundreds or thousands of wires. These numbering schemes are often particular to each facility, but there are tools to help make wire labels that will appear in the final controls cabinet.

This refers to making a joint in the middle of a wire or cable. If it is necessary for any reason then use a suitable connector or terminal block. Don’t use a twisted and soldered joint.

Line diagrams, also called “schematic” or “elementary” diagrams, show the circuits which form the basic operation of the controller. They do not indicate the physical relationships of the various components in the controller. They are an ideal means for troubleshooting a circuit.
