Hello, Late to the Game,
Your post about success with the bus wire tells me that you can learn just as I am learning. You see, I am a old retired academic. Reading 2500 year old authors' works doesn't prepare one to fix things, and I had long been convinced that I could not do so. But trains helped me learn and, more importantly, helped me learn that I can learn and can succeed. Oh, yes, I still work slowly and patiently, and I take pictures as I go to help an old bean remember things. I have made mistakes (some quite hilarious), but the learning is the best part.
