Don't Be Baffled by Your Electrical System--Handle Repairs and Improvements with Ease

With clear illustrations and simple explanations, Don Casey shows you exactly how to install wiring . . . make good, safe connections . . . match your battery bank and alternator to your needs . . . troubleshoot problems quickly . . . avoid shore power problems . . . and more--all without a lot of technical jargon.

"Don Casey's book provides clear guidance on how to create and maintain a robust electrical system. Don's lucid explanations and numerous illustrations make what is normally mysterious and invisible--electricity--into something the reader is able to understand with confidence. An excellent addition to the sailor's seagoing library."--Chuck Hawley
