Alternator removal, everything is clear ready to remove and it will not budge?

We removed all of the bolts nuts etc, to remove the alternator. And the connector and a plug in back of the alternator. And the plus to the Battery cable. Everything is clear, ready to be removed, and it will not budge. Is there a harness or cover, or anything else that could be in the way? We also removed the belt and dropped down the air compressor for more room and jacked up and removed the inside panel.
