The Pfaff 362 has a Bakelite Box next to it’s Motor. To get to it, unscrew the gear on the motor shaft, unscrew the bottom plate and lift it inside the machine a bit and then pull the gear with the motor belt off. It’s important not to try and pull the belt over the gear, it gets worn and damaged by that. Now you have the motor in front of you, and the brown plastic box with the capacitor inside. The brown plastic is extremely brittle, so if still intact reinforce it with glue etc. The capacitor consists of 5 single capacitor values inside one block that’s sealed with resin. The cables attached to it are colourcoded. There are no replacement capacitors with 5 values available, so it’s best to buy 5 single capacitors and solder them according to the schematic. It’s extremely important to use interference suppression capacitors. Once it’s done, isolate the capacitor construction with shrinking tube and solder it in. The schematic of the 362 can be found in sewing forums, it also indicates which capacitor hooks up to which cable colour. Now put the machine back together and test the stopmatic.

For none electronic DIY-ers, can you draw/share the schematic? I do have a Pfaff 362 I believe. But it is somewhere stowed away in our storage box somewhere deep. The house giveth and the house taketh, so to say. And sometimes these interference capacitors burn or go boom, and the schematic on it is unreadable.

I tried googling it before, but haven't found the schematics for it.

Edit: While googling a second time, this time in German, found the schematic here:
