I started hearing those Lucas jokes in 1964 when I started working on friends' MG's and big Healeys when I was in high school. British cars needing repairs were in abundance.Their electrical systems were simple, simple to diagnose, simple to repair and had a logic to the color coding that was easy to memorize and almost exactly the same for all British cars. (almost as simple as the Model A's, flat head Hudsons, flat head Mopars and Allis Chalmers that we maintained on the farm and I was too naive or worse to be put off by an MG)) After time in the Air Force, I became a full time British car mechanic, owner and racer. I owned a wide variety of them from the lowly Morris Minors and Spridgets to XK's. The electrical jokes, and the SU carb jokes/mysteries/frustrations/misinformation were probably good for my business, though I didn't exploit them because I loved those cars. People were afraid to work on them, or had attempted to work on them. Those were great days, and all those cars that were ridiculously cheap then are now fetching prices that put them out of my range. A few British car owners have always come off as ostentatious to me, unlike the generally seasoned, yet down-to-earth Model A people.
