|This course promotes the concept of troubleshooting and repair of systems using schematics and wiring diagrams. With a focus on troubleshooting techniques and the concept of internal isolation, attendees participate in the recognition of components and circuits including diodes, capacitors, transformers, relays and more. The latest in ANSI diagrams is discussed, which includes understanding ladders, logic, keys and legends. Circuit board technology in troubleshooting the system will also be discussed. The course has 3 lab exercises covering using a schematic to identify faulty components, converting a line diagram to a schematic and making a schematic by tracing the system wires.
