Automotive
Relay Circuit Guide book on PDF
Learn the basics and
advanced concepts of using automotive relays to do pretty much anything. There
are instances where you need to rewire a fan cooling motor, A/C blower, turn
signal or any other circuit on your older vehicle. Or you’re simply adding some
aftermarket component and need to use a relay. This book on pdf goes a long way
into showing you how to wire and the operation of many relay circuits. Use it
for your own benefit.

Automotive Relay Circuit Guide
(Includes circuit
explanations, how current flows and how to wire relays from the ground up.)
By Mandy Concepcion
This book is a
comprehensive work on automotive relays and their circuit analysis. The book is
also a companion to our Video-DVD series of the same title. Here, we analyze
how automotive relays are connected with their peripheral components. Each
section starts with the specifics of the components used in that circuit and
then there’s a deep analysis of how current flows on the circuit. The idea is
to first explain and give the reader the particulars of each circuit, then go
deeper and analyze why the circuit behaves the way it does, how to diagnose it
and how to connect it in case the whole wiring is missing, obsolete or simply
was never present to begin with. Special thanks to Carmen Diaz for her
invaluable input on the cover layout, structure, arrangement and proofing.
