Hello! I have purchased a used punching machine of the brand Sandt, model 410 from 1974. However, there seems to be an electrical issue with it. In order to troubleshoot it, I need a wiring diagram, which I currently do not have. Is there anyone here who has such a diagram or knows where I can start looking for one? I have already contacted Sandt, but they couldn't find a wiring diagram for such an old model. I would appreciate any tips or suggestions.
