Corequisite(s): None

This course is designed to prepare students with the fundamentals needed to study, diagnose, and repair all automotive electrical and electronic circuits and systems. Students study basic electrical theories, basic electrical circuits, common electrical components, troubleshooting methods, use of basic test equipment, diagnosis of faulty circuit operation, wiring, use of wiring diagrams, automotive batteries, lighting systems, and electrical accessories. The laboratory component of the course includes various activities that follow the guidelines of the National Automotive Technicians Education Foundation (NATEF) and the National Institute for Automotive Service Excellence (ASE).

Student Learning Outcomes of the Course:

Explain and demonstrate the relationship of AC/DC voltage, amperage and resistance (including all units of measurement) and be able to apply Ohm’s and Watt’s Laws to the construction, operation and troubleshooting of automotive electrical circuits.
Identify and explain the operation and relationship of common electrical circuit components and the seven circuit conditions as they apply to: series, parallel and series/parallel automotive electrical circuits.
Verify proper operation and troubleshoot electrical circuits/components using a digital volt-ohm meter (DVOM), test lights and jumper wires.
Read various automotive wiring diagrams to identify circuit components and use as a “road map” to assist in troubleshooting electrical system circuits and problems.
Demonstrate the knowledge of automotive starting battery construction, operation and performance ratings. Apply knowledge to safely perform maintenance procedures, all industry standard diagnostic tests and replace batteries within manufacturer’s specifications.
Demonstrate knowledge of the construction and operation of common automotive lighting systems and apply this understanding to troubleshoot and repair malfunctioning circuits and components.
