Check your fuse box. It's probably a bad fuse or relay. If all is good then clean the ground straps to the frame.

Does the charge light turn on when you just turn on the key? If not that needs to work, that is part of the excite circuit.

High possibility, is it a new or re-manufactured alternator? If it's not too much trouble, take it off and have it tested, that will tell you if the alt is bad or you have a broken circuit in the charging system.
