Narrative:

On climb out of stl, at approximately 5000 ft MSL, electric smoke indication on cap. I was flying, captain ran checklist. Captain then took aircraft and had me re-do checklist. Upon completion of checklist, I declared an emergency with ATC, requesting return to stl. I then notified flight attendants of situation, made an announcement to passenger, and contacted flight control. As we descended through approximately 3000 ft electrical smoke light went out. On short final lowered gear by re-engaging acw generators. Landed without incident. Returned to gate without evacing passenger, as light out and no smoke in cabin. Maintenance notified of problem. Upon completion of their tests, problem did not recur so aircraft was returned on line.
