This student instruction manual was written in conformance with selected criteria for programed instruction books as developed previously for various military training courses. The manual was developed as a part of "A Study of the Effectiveness of a Military-Type Computer-Based Instructional System When Used in Civilian High School Courses in Electronics and Automechanics" (VT 006 916). The material concentrates upon knowledge required for logical and systematic gathering of symptoms, analysis of these, and a logical step-by-step methodology of isolation to a section, a component, renewal and replacement or direct repair of the component and then an operational check to determine that the automobile will perform satisfactorily. Subject matter areas and sub-topics include (1) ignition system, functional description and components of the ignition system, (2) fuel system, purpose of the fuel system, fuel components, and operational combination requirements, (3) Engine analysis, basic starting tests and detailed tests for hard starting, and (4) tune-up procedures, types of test equipment, engine tune-up, and road testing. The activities included are those which can benefit the most from a systematic approach applicable generally to any problem which might arise. (HC)
