Tony Candela's auto wiring books
I've spent the past 50 years give or take working on old cars, trucks and motorcycles (for only my own entertainment.) So much of the electrical was duplicating factory systems but when it came to really understanding the reasons for doing or using certain parts there was a void. I picked up Tony Candela's books and so many things came together after reading them. It also allowed me to do those upgrades like using breakers, fuses and relays PROPERLY, creating a harness that is not going to burn the car to the ground but the best part is now having the knowledge of WHY those things should or should not be done. Both books are written with enough technical jargon and explained theory in such a way that it makes perfect sense but doesn't put you to sleep. A bit of humour and an author that surprised the heck out of me when he personally responded to an e-mail question I had about a custom charging system. If you are also a hotrodder you gotta read these books. I won't call them those cliché words like bible, go to reference or anything....but darn, they are. Thanks Mr. Candela

Well worth the money and an excellent manual to boot
I basically got this book not for a car but for getting some information to help me work on my motorcycle and as I could not find any decent motorcycle specific books including the Haynes manuals that have really gone downhill, I decided to look at automotive books since they are basically the same as far as the automotive principles are concerned. After looking at a few other automotive books including a so-called interactive video which turned out to be a hotch potch collection of PDFs, I finally ordered this book based on the reviews that I read. Boy a do I like it? It is an excellent book that takes you from the very basics to more comples explanations in a properly structured step by step explanations with very clear colour pictures (unlike many others that have grainy and incohesive black and white photos). my only peeve is some of the units are in stone age system that they still use across the pond and it would've been a good idea to show them both (e.g use the old stone age system for the native hill billys but also have the proper units used the world over shown in brackets or atleast have a quick and easy conversion chart in an appendix). Having said that, it does not take away from the actual information and easy to understand approach of the author. I would definitely recommend this book over any other one I have bought and despite the ston age units (not many anyway) I still think this book is worth 5 stars; so well done Mr Candela, maybe you could put a similar manual for motorcycles and I don't mean the Hardly effin Movinson tractors but proper bikes used around the world ;)

Muito bom.
Bem equilibrado entre explicação simplificada e definições técnicas. Atende mesmo a quem tem pouca noção de eletrônica. Ensina fórmulas, técnicas de soldagem, como crimpar cabos, entre outros. Atendeu perfeitamente às expectativas.

Probably not a great book if you know what you are doing. I know cars inside and out, and have even rebuilt differentials and two engines. I don't know squat about wiring and electrical, however. Going back to square one for me was tough to do, ego-wise, but my more or less thorough automotive education has large holes that need to be filled. I am used to working out of manuals and such that are very tech oriented, but I knew zip about the tools and terms used for electrical work. This book got me up to speed enough to allow me to continue self teaching with more advanced manuals. I now understand most of the basics and am no longer reluctant to work on my aging wiring harnesses and connectors. Not a bad purchase at full price, but as a Kindle book it was a steal. At this price, if you do not like it you are not out very much. I though it was very useful and now have a much more evenly balanced skill set.

Simple
Básico, en realidad no te enseña a diseñar un círcuito desde cero, solo te dice que es cada componente pero no más... He estado buscando libros más especializados en el tema pero no he encontrado, lo recomiendo solo si no sabes nada del tema.
