I have an old Pfaff 97 sewing machine that suddenly started to run at full speed regardless of the pedal input.
I disassembled and checked the foot pedal and it is working perfectly.
I took out the motor and found a strange capacitor/filter. Can anyone help me decipher the schematic so I can replace it using individual capacitors?
The black and white wires got shorted and this is the problem.
(from my understanding of German language: "grau" = grey; "gemeins. Pol weiss" = common pole white; "sw" = black; I have no idea what b in a circle with the grounding symbol means as the motor has no grounding)
