AUT 242 - Automotive Electricity II (4 CR.)

Course Description

Introduces electricity and magnetism, symbols and circuitry as applied to the alternators, regulators, starters, lighting systems, instruments and gauges and accessories. Part II of II. Lecture 3 hours. Laboratory 3 hours. Total 6 hours per week.

General Course Purpose

Automotive Electricity II focuses on automotive accessory systems. This course will emphasize the use of electrical wire diagrams to aid in the diagnosis and repair of electrical concerns in the accessory systems. In depth diagnosis and repair procedures are covered using DMM’s, scan tools, and oscilloscopes.

Attention is given to determining electrical systems defects, their probable causes, and what repairs are required for correction. Lecture demonstrations will cover theory and operation of accessory systems.

Students will develop an understanding of various electrical accessory systems to include their function, operation, and service requirements. Laboratory experience will involve the use of diagnostic equipment for trouble shooting and correcting accessory systems concerns.
