All alternators need some form of panel mounted
pilot control for turning it OFF - they also need
overvoltage protection. If the alternator
has a built in regulator and you don't plan to modify
it for an external regualtor, then you need to wire
it as shown in http://www.aeroelectric.com/articles/bleadovm.pdf
If your alternator uses and external regulator, then
it can be wired in accordance with any of many classic
wiring diagrams like those shown in the back of our
book.
