I remember being stoked on this show. This was around the same time Karate Kid was one of the biggest movies out and my brother and I were all about anything martial arts, including this dumb show.
I honestly enjoyed watching this old ABC series on Saturday nights which stars "Buck Rogers" and WKRP's "Herb Tarlek" just to name a few. I also remember that show O'Hara --- which is the series Mr. Miyagi starred in.
I remember this show didn't last long at ALL but it was cool. The "Last Electric Knight" sound an awful lot like the "Last Dragon" which is where one of many films that brought Ernie Reyes Jr. to fame.
