Check all of your fuses (it is possible that during the install one of them could have been blown).
Recheck the alternator wires to be sure that nothing has been left disconnected or that a wire wasn't pinched of damaged during the install.
Have Advance Auto to recheck the charging system (could've been a bad alternator - It's kind of a long shot but very possible).
