Frustrated by the high cost of basic electrical work but nervous about tackling such projects yourself? Get sound advice and guidance from author Ed Sherman, who wrote and teaches the American BoatandYacht Councils certification program for electrical technicians. In Powerboaters Guide to Electrical Systems, he combines basic theory with step-by-step directions for troubleshooting problems, making repairs, and installing new equipment. Learn to

• Draw up a wiring diagram for your boat
• Locate and identify wiring and circuit components
• Select and use a multimeter
• Choose and maintain battery and marine ignition systems
• Troubleshoot starting, charging, and instrument problems
• Install DC and AC marine accessories, equipment, and electronics

“Ed Sherman's nationally recognized expertise in electrical systems in boats makes him a natural choice to train and certify marine electricians. . . . He believes, as I do, that doing it right the first time will surely enhance your boating experience.”--C. T. “Skip” Moyer III, Past President, American BoatandYacht Council

Ed Sherman is one of Americas best-known authorities on marine technology. He is the author of Advanced Marine Electrics and Electronics Troubleshooting and Outboard Engines and the coauthor of The 12-Volt Bible for Boats. As the senior staff writer for the American BoatandYacht Council, he plays a key role in defining that organizations national standards for electrical systems and certifying marine electricians to the standards.
