Electrical Circuits, Symbols, and Diagrams
Objectives • List the meaning of symbols used with OPE electrical systems. • Explain how equipment manufacturers use wire color codes to identify different OPE systems. • Explain what a wiring harness is used for.
Electrical systems used with outdoor power equipment (OPE) have diagrams and schematics available for identifying components, tracing circuit paths, and troubleshooting individual OPE operating systems. A successful technician must have a fluent understanding of the symbols used with schematics and diagrams. Each OPE manufacturer uses their own set of standardized wire colors. Technicians will develop an understanding of manufacturer-specific standards as they gain experience.
• Describe electrical diagrams and wiring diagrams. • Explain how to read and use diagrams used with OPE electrical systems.
