simple boat electrics

At home you can flick a switch and electricity will flow, as long as you pay the bills. A boat is more like an island: if electricity is used, it must be replaced; if things go wrong, you will have to fix them yourself. This book contains all you need to be a 12-volt troubleshooter. It gives some basic theory so you can understand what you’re doing. It majors on the seamanlike practices of anticipating and preventing trouble. And it shows clearly how to locate a fault, correct the problem if you can or adopt a get-you-home remedy if you can’t. Read it at home, then keep it on your boat’s bookshelf for when you need it most.
