• Tips on preparing for and taking the ASE test.
• The A6 ASE Test Task List, which lists the knowledge that a technician must have to pass the A6 ASE test.
• Complete Electrical/Electronic System, Battery, Starting System, Charging System, Lighting Systems, Gauges, Horn, Wiper/Washer and Power Accessories diagnostic information, symptom descriptions and probable causes,  testing procedures, and interpretation of test results; repair information, disassembly, cleaning, inspection, repair, adjustment and assembly procedures.
• A Practice Test, with all questions written in the ASE style. The answers to the Practice Test questions contain thorough explanations for each answer.
• A comprehensive Glossary, including all electrical/electronic system-related terms used in the Study Guide.

In addition to the easy-to-read text, the Delmar A6 Electrical/Electronic Systems Self-Study Guide contains dozens of useful illustrations, and like all Delmar Self-Study Guides, it is spiral bound, which allows the pages to lie flat for ease of use. You ll also find the Delmar A6 Electrical/Electronic Systems Self-Study Guide to be a handy reference manual that you can use on the job after you ve taken the ASE test.
