Automotive Wiring and Electrical Systems

Introduction

Automotive Wiring and Electrical Systems
Automotive Wiring and Electrical Systems

    Automotive wiring is not a topic to be taken lightly. In fact, a simple mistake can cause a fire in your prized vehicle. You’d be surprised if you knew what I’ve seen under the dashes of the nicest of cars over the years. You’d be even more surprised at how simple it is to avoid these pitfalls altogether and do it right the first time.

    So, why did you pick up this book to begin with? I mean, after all, automotive wiring is like calculus to most people! The answer is simple you picked up this book because: 

You need help troubleshooting an electrical problem. 

You need help installing aftermarket electronics. 

You wanted to become the expert in this topic.

 Most importantly, you want to be able to do all of the above safely.

    Again, this book is intended to demystify the practice so it won’t read like a college-level physics book. After you’ve read it, you’ll be able to do all of the above and so much more! To make the material easy to follow and learn, I’ve written the book so that each chapter provides you the knowledge needed to comprehend the following chapter. In addition, I’ve provided as many pictures and diagrams as I could, so that you can visualize my explanations. Finally, I’ve provided several step-by-step examples that you can do in your garage so that you can practice what you see in these pages.
