Course Description

Introduces electrical theory, schematic symbols, battery and starter theory, operation, diagnosis and repair. Covers proper repair procedures, component identification and service procedures performed on school owned vehicles and components. Audit available.

Addendum to Course Description

Students will study fundamental electrical theory. This includes series, parallel and series-parallel circuits, voltage, amperage, resistance, electromagnetism and circuit protection. Hands on use of volt-ohm-ammeters will be done in the classroom and laboratory. Students will learn fundamental theory of battery operation, testing, diagnosing and servicing. They will also study starter circuit operation. Diagnosing and problem solving will be done on school owned vehicles. Students will work with diagnostic test equipment to determine reasons for starter circuit failures. Students will study and practice various forms of wire splicing, repair and soldering techniques.

Intended Outcomes for the course

Upon completion of the course students should be able to:

  • Perform basic 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 repair electrical system problems relating to starting systems.
  • Perform electrical system repair of starting systems to professional and ethical standards.
