With Automotive Electricity and Electronics , students can explore how automotive electronics work, the role they play in a vehicle's normal operation, how and why technicians use test instruments, and common diagnosis and repair procedures. The text provides a solid grounding in the fundamentals of electricity and electronics, giving students the foundation they need to master advanced topics such as batteries, starting and charging systems, ignitions, and electrical accessories. Practical testing procedures are covered as well, including the use of both common shop tools and highly technical equipment. The text also includes up-to-date coverage of current systems, tools, and J1930 terminology.
