Vehicle - Auto - Truck - Heavy Equipment "Electrical Troubleshooting SHORTCUTS" The "How-To" Electrical Book! This HOW-TO book, "Vehicle Electrical Troubleshooting SHORTCUTS," is for beginner through professional auto, truck or heavy equipment service technicians who need more practical electrical troubleshooting training. This 250 page textbook combines the electrical troubleshooting training from Vince Fischelli's, 3-Day Phase 1, Advanced Electrical Troubleshooting Workshops and Seminars combined into one volume of 250 pages suitable for home study and shop use. Packed full of how-to electrical troubleshooting procedures that work and save testing and troubleshooting time which increases your profits. No more guessing about what's causing an electrical problem. Many have asked to buy a Phase 1 workbook since they were unable to attend a Phase 1 Workshop in Dallas. But the workbook was written to be used in the workshop, with a lecture and is not designed for self-study. Now this NEW book, SHORTCUTS, covering the Phase 1 workshop, is available in a fully self-contained textbook. Vince's new book is called "Vehicle Electrical Troubleshooting SHORTCUTS." You can buy it NOW for $78.00 plus shipping and handling. Seven Sections cover essential electrical principles, how to use a DMM and a tutorial on how circuits really work. SHORTCUTS then covers electrical troubleshooting techniques of battery circuits, cranking circuits and charging circuits using only a DMM and Current Clamp to perform these electrical tests on-the-vehicle. The last section explains how to read electrical circuit diagrams. Imagine repairing vehicle electrical problems in battery, cranking and charging circuits using only a DMM and Current Clamp. No need for expensive electrical testers dedicated to tests these circuits. SHORTCUTS provides explanations on how these circuits work and presents innovative electrical troubleshooting procedures for batteries, cranking circuits and charging circuits that anyone can follow to find the cause of an electrical failure. Keep in mind, all that is needed to do this level of in-depth electrical troubleshooting SHORTCUTS and repair is a DMM and a Current Clamp.  SHORTCUTS Content Outline SHORTCUTS Section 1: 26 Pages - 11 Illustrations "Essential Electrical Principles" This first section is an introduction to essential electrical principles for those who have never studied electrical principles before.
