Auto-Electric Repairs Explained

by Mandy Concepcion

This book, Auto-Electric Repairs Explained of which there's also a companion DVD by the same title, is a dedicated work centered in automotive electric diagnostics. 99% of the auto-repair duties for an auto technician will be of the electric nature, not necessarily electronics. Electronic is also a part of auto repairs, but covered on another couse-manual-DVD by the same author. This book concentrates on the techniques relevant to repairing open and short circuits on actuators, such as motors, power feed, grounds, and other electrical faults.Techniques such as current ramping, voltage drop, scope usage, sound tracing, current draw test and many others are covered. This book and our other electronics courses 1 & 2 are a must have for any tech or DIY interested in delving into the world of electric and electronic auto repair.Special thanks given to all the techs and shops who supported my investigations on this technology, and to my wife for her support…God bless…Table of ContentsThe OBD-II DLC or Data-Link-ConnectorElectric and Electronic DiagnosticsElectron Flow TheoryHow to Do a Voltage Drop TestHow to do a Current/Amperage TestStressing the circuitHow to do a Resistance TestDoing a Continuity TestFinding Battery Parasitic Current DrawElectric Ground & Chassis Ground TestingSensor Ground Electric TestingUsing the Fox & Hound (tone generator) to find open circuitsCurrent Ramping Electric TechniqueCurrent Ramping a Fuel PumpCurrent Ramping the Ignition CoilCurrent Ramping an InjectorCurrent Ramping Compression TestStarter Electric Diagnostic TestAlternator Wire Electronic Voltage-Drop TestBattery Power Electric TestBattery Current Draw Electric TestIgnition Coil Current Ramping TechniqueAutomotive Electric Wiring DiagramsElectric Cooling Fan Wiring Diagram InterpretationIgnition Switch Electric Test
