Here is an excellent manual for the boat owners and marine technicians prepared by Ed Sherman. The declared intention of the author, who is the senior writer of the American Boat & Yacht Council, was to provide readers with necessary knowledge on the proper troubleshooting of the modern complex electrical systems installed on boats and protect such electronic installation from the interference.
The readers of this book will also get to know how to eliminate various charging and starting problems, and how to track down the wide range of wiring, grounding, bonding, and corrosion problems. We would treat it as the top notch for every advance amateur electrical do-it-yourself boater. Though it is not too big and thick, this book is densely packed and full of valuable technical information related to the corrosion, RFI, electrical leakage and other important issues requiring the immediate attention of the persons handling and maintaining the boat. It features very good and high-quality graphics and images.
It is not actually a primer on electronics but rather perfect textbook for those who have some fundamental understanding of electricity. Do not miss this one - you know, boats always have some electrical issues and you' better get prepared to fix them yourself.
