How to Diagnose and Repair Automotive Electrical Systems

Automotive electrical systems are too often a mystery, as much for the experienced professional as the weekend do-it-yourself mechanic. However, they simply don’t have to be—the mass of wires under a dash and beneath the hood of a car or truck, need no longer be feared by everyone except the most elite technicians. The popular book, “How To Diagnose and Repair Automotive Electrical Systems,” by Tracy Martin, explains the principles behind automotive electrical systems and provides an in-depth, but simple-to- understand description of how each major system and its components operate.

This helpful how-to book also combines an easy- to-use, at-a-glance format, with simple, everyday language so that electrical concepts, usually overwhelming and boring in a typical textbook format, become effortless, enjoyable, and easy to follow. The book also provides uncomplicated, practical instruction on how to diagnose and repair common, but rarely understood, automotive electrical malfunctions. In addition, the book is packed with lots of large full-color diagrams and photos for extra visual reinforcement of ideas and concepts.

From basic electrical theories like Ohm’s Law to easy deciphering and reading of complex-looking wiring diagrams and applied practice on sample electrical scenarios, author and ASE (Automotive Service Excellence) Certified Master Technician, Tracy Martin, provides a refreshingly welcome guided tour of automotive electrical systems.

This invaluable guide also details the various tools, such as digital multimeters, test lights and logic probes, used to evaluate and troubleshoot a vehicle’s electrical system, as well as sharing handy tips to help banish costly electrical gremlins. Charging systems, including those found in the three big U.S. manufacturers’ vehicles, Ford, GM, and Chrysler, are covered in detail, as are ignition and computer systems. Plus, a chapter on wiring diagrams teaches, in simple sequential steps, how to actually read one, without mystery or frustration, and provides several helpful and entertaining wiring diagram exercises as well. All chapters feature practical, everyday examples of common electrical problems encountered and how to find, diagnose and repair the real problem right the first time.

Finally, thanks to Tracy Martin’s innovative book, with its unique approach, easy-reading style and simple-to-understand format, vehicle owners and repair technicians never need get lost in the dark again with only a faulty electrical signal or ridiculously confusing wiring diagram as a guide. The knowledge contained in “How To Diagnose and Repair Automotive Electrical Systems” is simply the best tool available for the job of understanding electrical systems and diagnosing electronic and electrical-related problems in any vehicle.
