havier,
Please don't take this the wrong way, but..
Unless you can locate someone experienced who can coach you in person, you will need to consult as many reference books to understand how to work on an AC system.
There are significant risks of which you should be aware of less you screw something up or injure yourself.
Some things are best not done by the beginner without preparation. AC charging is one of them, IMHO.
Good luck
Steve
