Mike, also, when you are re-reading your initial post in this thread, you surely must realize that it is not written in English sentences.
You are starting the post somewhat coherent but not super specific with 'So we're doing this', but then it already falls apart after 'old Chinese folding': is 'e' a remnant of a word, a word from a different language, the remainder of something you deleted, an interjection that your transcription program picked up , or what? Then comes 'Replacing control box'. Since it starts with a capital 'R', is punctuation missing, and there was a new sentence? What happened to the end of the first sentence, that part that explains what old Chinese folding thing you are doing something to?
The second sentence is not much better, it starts like English with 'The switch that says A&E on it', but then peters out unintelligibly 'for assist in a throttel (why this spelling?) back-and-forth.' It just doesn't make any sense. The spelling would indicate that you are actually typing or stringing letters together, so what we are reading is not the output from a transcription program.
The next sentence makes sense, except that a switch is not something that plugs into something else.
And then the whole post just suddenly ends with 'Any idea where That might be ', no punctuation. Was there more to be written, but it got deleted, or not transcribed? You are certainly not asking us where your control box might be, but what are you asking? And why is 'That' capitalized?
I've read posts by people who can't be bothered or can't get it together enough to use punctuation; whole paragraphs are just one jumble of phrases, but often one can make sense of what they mean. Your posts are worse. You need to make a better effort at communicating.
