ElectraWoman (Deidre Hall) and DynaGirl (Judy Strangis) aired in 1976 on the Sid and Marty Krofft show in the 1970's on Saturday mornings. I believe there were only 6-7 episodes. (Maybe not even that many.)
It was cancelled very shortly after it aired. Deidre Hall, now plays "Marlena" on "Days of Our Lives".
