Look for colors from the legend of the diagram. Colors are used to represent the type of wire used in the circuit. Black is a good indicator for ground wires and red is an indicator for power or hot wires.

Locate symbols from the legend of the diagram. These symbols represent different components in the circuit, such as resistors, capacitors, and diodes.

Read any notes and descriptions carefully. Sometimes, written descriptions are included to help explain the function of a particular component.
