A long bolt passes through the alternator mount, then through the alternator, then through a little bracket to which a bunch of wiring harnesses and a metal tube are all connected, correct?. There should be a 13 (?) mm nut on the back of this collection, and it is hard to reach because of the plastic bracket. Try using a long set of socket extensions and a u-joint extension; long enough to bypass the obstructions in the way.
There is also a formed (bent) metal bracket that this above assembly attaches to and is fastened at the back of the alternator. Remove the nut that attaches it to the alternator.
The alternator should now be loose enough to carefully rotate it out of the mounting area and allow you to remove the electrical connections.
