Course Description

Covers reading schematics, starting and charging system theory, operation, diagnosis and repair. Includes proper repair procedures, component identification and service procedures performed on school owned vehicles and components. Audit available.

Addendum to Course Description

Students will review basic electrical concepts studied in Electrical Systems I. Students study theory of charging system operation, testing, diagnosis and servicing. Wiring schematics and diagrams will be discussed as well as on-car troubleshooting of wiring problems. Students will become familiar with the operation and testing of lighting systems, power windows and door locks, windshield wipers, defoggers, and instrument gauges. Theory and use of semi-conductor devices will be discussed.

Intended Outcomes for the course

Upon completion of the course students should be able to:

  • Perform select electrical system inspection, maintenance, diagnosis and repairs relating to starting and charging systems.
  • Access and utilize repair information in a rapidly changing technology.
  • Develop and implement strategies and processes to solve electrical system repair problems relating to starting and charging systems.
  • Perform electrical system repair of starting and charging systems to professional and ethical standards.
