Dewey:
A Tortoise machine operates in one direction with one polarity, and in the opposite direction with reversed polarity. I wonder how you are able to get them to go in two directions using a single-throw switch. Can you show us a wiring diagram?
I have re-read your answer, and if I understand you correctly, you change the polarity of the wires manually, at a terminal strip, when you want the machine to operate in the opposite direction? That seems like a lot of work that could be done with a double-throw switch. Or am I misunderstanding you?
