I have had my 65 MGB since 1985, and have done all the work done to it over the years. Now that I am dealing with a 45 year old wiring harness, I thought it was a good time to see how I can keep the old girls wiring from emitting smoke and fire.
I was really interested in how to incorporate relays into the electrical system, and this book does a great job of not only telling you how to do it, but provides several photographs to help you along.
There is even a chapter on electrical theory and how it relates to automobiles. Aside from this chapter, the book is written in plain English. There are lots of great ideas to be had in this book, and I would consider it an essential book to have along with the Bentley manual, and of course the Chilton manual.
I would recommend getting this book while it is still available, and still at a decent cost.
