Upgrade your electrical system by answering three simple questions and by installing the equipment to support your answers, you will have all the electrical power you need.
Operate your electrical system by learning how to determine the amount of "fuel" your batteries contain and how to recharge them properly.
Troubleshoot your 12-volt electrical system by following simple step by step procedures for troubleshooting circuits containing failed lights, electronics, chargers or batteries.
Few people want to read a technical book but they want answers to their problems. Managing 12 Volts provides a simple method to determine how to upgrade an RV or a boat. Worksheets are provided enabling you to determine quickly how to improve your 12 volt electrical system. Few people understand how batteries work or how they should operate their system, so the important factors affecting batteries are highlighted and a chapter is devoted to the operation of various vehicles.
It is frustrating having something that does not work properly and this is especially true of electrical systems. Managing 12 Volts relieves this frustration by providing answers to why your batteries fail to support your electrical needs and provides solutions that will enable you to have all the electrical power you require.
Finding information is easy in Managing 12 Volts because the book can be quickly scanned to understand the basic points or carefully read to understand the important details of batteries and charging systems.
This book is for RV electrical sytems, boat electrical systems, battery chargers, and 12 volt batteries.
Chapters Provide Helpful Information
Chapter 2 helps you to determine your electrical requirements. Tables and worksheets makes it easy for you to figure out how much energy your RV and boat uses each day. If you understand your needs it is easy to determine how much battery capacity you require.
Chapter 3 explains how a battery works and Chapter 4 presents different types of lead acid batteries such as automotive starting batteries, maintenance free batteries, deep-cycle batteries, Gel batteries, and absorbed glass mat batteries. This chapter has a simple worksheet that helps you to determine the battery capacity you should have to power your electrical appliances.
Chapter 5 explains battery charging. The standard charging systems on RVs and boats fail to recharge your batteries properly when dry camping or when anchoring. This chapter explains about multi-stage chargers, which do an outstanding job recharging batteries. Alternations made by Balmar and Hehr Powerline, multistage battery chargers by Xantrex, which makes Truecharge, and inverters with high output changers by Prosine and Xantrex Freedom recharge batteries quickly and efficiently. They are available at places like Camping World and West Marine. This chapter also explains solar panels and wind generators.
Chapter 6 explains electrical monitors that indicates how much “fuel” is in a battery and tells you when to recharge your batteries. These monitors takes the mystery out of a 12 volt electrical system and will enable you to successfully manage you system.
Chapter 7 helps you to design and operate an efficient 12 volt electrical system. It lists the keys to electrical self-sufficiency and makes recommendations on how to upgrade an RV or a boat’s electrical system. These recommendations range from ideas for a small RV or camping trailer were its owner does not want to spend a lot of money to upgrade their system but wants improvement to recommendations for large RV and boats were their owners want the best electrical systems. And in the case of the large sailboat owner he wants an electrical system that will allow him to cross oceans.
Chapter 8 explains electrical circuits and chapter 9 explains in simple step by step procedures how to troubleshoot circuits containing failed batteries, electronic, lights, chargers, and how to look for electrical leakage.
Managing 12 Volts is a valuable reference book to have on your RV or boat to help you to troubleshoot failed electrical circuits.
Reviews
Published Reviews Acclaim Managing 12 Volts
“Managing 12 Volts by Harold Barre is one of the better books of this genre. Barre understands that batteries’ “behavior” is the weak link of DC systems. The boat is worth buying for this alone. Managing 12 Volts is excellent for getting a handle on the basic battery issues of DC systems.”
Nigel Calder in Sail Magazine
Author of Boatowner’s Mechanical and Electrical Manual
