We have opened up the foot controller to clean and rewire it and noticed that there is a piece of electrical tape inside. It looks like it is keeping metal from hitting metal so it won't short out. Am I missing a piece here or is the tape a common thing? I am really hoping to get to use the original foot controller. I hope these pics are helpful. Thank you!!
