This course provides classroom and laboratory hands-on activities where students building on material learned in AT108 Automotive Electrical Foundations use wiring diagrams to examine headlight, taillight, stoplight and turn/hazard light for operation and repair. Students are taught to use advanced diagnostic techniques to diagnose and repair electrical circuits associated with instrumentation, horn systems and wiper/washer systems. Students will learn on modern training aids using factory service procedures. The laboratory component of the course includes various activities that follow the guidelines of the National Technicians Education Foundation (NATEF). A library/internet research written project concerning some aspect of an automobile’s electrical system covered in this course will be assigned and is an integral component of this course.
