What is the difference between a schematic and a wiring diagram?
Schematic diagrams and wiring diagrams are representations of electronic circuits. Both diagrams can show the same electronic circuit, and both are relied upon for information about the circuit. Each will represent the whole circuit, but each will be used by different people.SchematicThe schematic is a representation of how the circuit works. Regardless of how the components are physically laid out, the schematic shows the logical order of how they are used together.TroubleshootingThe technician uses the schematic to understand the circuit as a whole and makes logical deductions based on this understanding.Wiring DiagramA wiring diagram is a wire-for-wire representation of the circuit. Without regard to the logical function of the circuit, all wire runs will be shown.WiringThe person assembling, installing or troubleshooting the circuit will use the wiring diagram to make sure all wires are connected properly.DifferenceThe difference is that a schematic is used to understand the circui
