I screwed them back on just for you, Miriam. You can see the stuff that dripped out of the cooked capacitor below, just like splats from a candle. Easy to spot.
The other image is the foot control for a Necchi Supernova. Same symptoms, start running on its own, no control over speed, etc. Reason not so apparent when the culprit is hidden. The cap is gone, you can barely see the stumps of the leads near the screw terminals, plus remnants of the mess from the cap.
Yeah, I forgot to mention the Supernova in the last post - that's 4 machines that needed surgery - electomies?- of the 8 I bought over the last couple of months.
I opened up the 201K pedal, there was no cap in there, I was wrong about that.
