Lincoln wont start

What is your question?

I went a got a brand new battery and when I try to start it I get nothing at all. With the hood up, you can hear a tiny little tick, but that is it. Is this a starter if I never had any sign it was going out? Or could it be cylinoid? Or is there a way it could be the "brain box" it is loaded with all the fancy gadgets and gauges etc. Any help appreciated!
