The 12-Volt Bible for Boats is a clear, nonthreatening introduction to the 12-volt electrical systems used on small boats to power everything from reading lights to bilge pumps. This second edition is thoroughly updated with respect to modern batteries, breaker and panel design, alternative energy sources, and troubleshooting equipment, but it retains the fundamental simplicity that is the source of its enduring popularity (more than 100,000 copies sold).

A primer on 12-volt electrical systems for boatowners who are not skilled electricians. Explains how 12-volt DC electrical systems work, how to maintain them, how to recognize an electrical problem, how to trouble-shoot to locate the problem, and what simple tools and techniques you'll need to fix it.

The rapid progress in research on mass-losing pulsating stars has now taken us far from its early photographic light variation study to the world of massive photometry and interferometic observations. However, some fundamental problems - such as the pulsational mode and the mass-loss mechanism - remain a mystery.

More and more sailors and powerboaters are buying and relying on electronic and electric devices aboard their boats, but few are aware of proper installation procedures or how to safely troubleshoot these devices if they go on the blink.
