I'm guessing that's a joke username/post... but I like it!
10+ years ago I called the AA as my MR2 Turbo wouldn't start, the AA guy jumped in the car and tried to turn it over for about 5 minutes until I asked him to stop as my throttle cable was starting to smoke!! The guy couldn't fix it so towed the car to a garage, after explaining the problem the guy undid the earth strap, cleaned it, bolted it back on and the car was fine after that. Apparently the smoking throttle cable gave it away as the current was finding the next best route to earth... suprised the AA guy didn't know that. Since then I use other companies but that was a long time ago so maybe they've improved since.
