The 12-Volt Bible for Boats is a complete introduction to the 12-volt electrical systems used on small boats to power everything from reading lights to bilge pumps. Written for boaters who are not skilled electricians, it clearly explains how 12-volt systems work and how to install, maintain, and troubleshoot them.
This second edition has been thoroughly updated to include the latest on marine batteries?including AGM and gel-cell batteries, multistage chargers, inverters, new wiring conventions, alternative energy sources, and modern test gear.
