I see this is an old post but I will try anyways. I had a Singer red eye given to me. My fiance put a motor on it. I used it before but forgot how. I think I plugged it into the block cord with light and motor plugins. I recently went to use it plugged it in the motor section but it didnt work .I tried it in the light section but it wont stop running until I unplug it. I have sewn on this machine before and at my wits end as to why I cant figure it out. Why is it running when I plug it in the light socket of the block? I recently had surgery and was put to sleep for it so maybe I have a mental block, I dont know. If anyone can help I would really appreciate it. Thanks
