Portland Community College | Portland, Oregon

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.
