The 12 Volt Doctor's Practical Handbook by Edgar J. Beyn provides a clear and useful electrical troubleshooting guide. With this 'Doctor' in hand you can fix electrical problems on board before calling expensive outside technicians. You can learn basics of electricity, maintain your own 12 volt system, understand how to use zincs effectively, and isolate and repair hard to diagnose electrical problems. The chapter on Electrolytic Corrosion is the most definitive text available on the subject. Plentiful, simple instructions make the book easy to use even if the reader has no previous electrical experience.
