I use the digital on some things.
The small items like - - where does this spring hook back up and in which hole in which lever and was it the long end or short end -- I prefer color coding with a dab of paint. EX: blue end goes to the third hole because it be blue too.:laughing: yellow end goes to that piece over there with the yellow hole. Throttle cable end came from here with the dab of white paint. Just a few minutes can save all kinds of frustrations and the camera backs up my mis-understanding too.
Did you ever try to read a mod. no. or serial on the back side of a washer or dryer with it against the wall? Well, that's the first thing needed so even though not handy lets just do it. You take a picture in a mirror with your digi and then on your pooter flip it and the backward inverted numbers will be uprighted.
