  1. WIRING DIAGRAMS

  2. TYPES OF WIRING DIAGRAMS • WIRING DIAGRAM • ENTIRE VEHICLE • SINGLE CIRCUIT OR SYSTEM • SCHEMATICS • HARNESS (ROUTING) DIAGRAMS • COMPONENT LOCATORS

  3. BLOCK DIAGRAMS • GRID DIAGRAMS • SCHEMATICS

  4. WIRING DIAGRAMS • IDENTIFIES WIRES , CONNECTORS AND COMPONENTS • SHOWS POWER DISTRIBUTIION • SHOWS GROUND DISTRIBUTION • SHOWS ENTIRE CIRCUIT OR SINGLE CIRCUIT • SHOWS DETAILED INFORMATION • PRINTED CIRCUIT BOARDS

  5. ELECTRICAL SYMBOLS • Symbols represent actual components • Sometimes shows basic operation • “Legend” interprets the symbols • Some show actual drawing of component

  6. COLOR CODES AND CIRCUIT NUMBERING • wire/circuit identification • Wire marking, tags, color, tracers • Standarized color code SAE or Manu. • Diagram circuit numbering • Wire gauge

  7. COMPONENT LOCATORS • Factory service manuals • Aftermarket manuals • Harness Views • Component views • connector views

  8. TROUBLESHOOTING • Must use logic • consistent method • Parts of circuit
