These conductors must be yellow throughout the entire circuit, including wiring in the control panel and the external field wiring. • White or natural gray represents a grounded circuit conductor. • White with blue stripe represents a grounded DC current-carrying circuit conductor. International and European standards require you to use light blue for the neutral conductor. • White with yellow stripe represents grounded AC current-carrying control circuit conductors that remain energized when the disconnecting means is in the OFF position. For additional circuits powered from different sources that remain energized when the main disconnecting means is in the OFF position, you must use striping colors other than green, yellow or blue to uniquely identify the grounded conductors.

Now that you have replaced the valves, cut the seats, and confirmed it all makes contact with each other, your engine will start easier, produce more power, and give you less trouble as you work them.

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.

For example, once the electrical designs are complete, they must be built by an electrician. Therefore, it is your responsibility to effectively communicate your design intentions to the electricians through drawings.

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.

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.

The control panel may be isolated but the lamp will require power so that the engineer can see while working on it.

However, an exception allows you to install a splice in leads attached to electrical equipment, such as motors and solenoids.
