What ever happened to the actor that played keith thelma husband on good times the sitcom from the 70ies.

If you meant Keith Anderson (the only character named Keith in the Good Times series), that part was played by Ben Powers (born February 13, 1949 in Yonkers, New York). Good Times (1978-1979) was only his second professional acting gig, having been on Great Performances (1975), and a Laugh-In reboot (1977). He continued acting in 12 other movies and TV series from Cheech & Chong's Next Movie (1980) to his last role in The New Mike Hammer (1984-1985). He's now retired, living in Rhode Island.
