Auto Electrical and Diagnostics: Testing Circuits, Reading Codes, Tracing Faults Like a Pro

Electrical gremlins don't have to beat you. This system-specific guide teaches the DIYer to test circuits, read codes, and trace any electrical fault like a pro - with a multimeter and a method, not guesswork. You'll learn how to: use a digital multimeter with confidence; master voltage-drop testing - the professional's secret weapon; read wiring diagrams; test the battery, alternator, and starter; test sensors, relays, actuators, and solenoids; work with CAN bus and OBD-II; read trouble codes, live data, freeze frame, and Mode 6; and trace opens, shorts to ground and power, bad grounds, and parasitic key-off battery drains. With 55 full-color figures, real diagnostic case files, and a systematic method that finds the fault instead of throwing parts at it.
