Bernina 540 Footpedal wiring etc.
My 540 has speed controller electronic components built into a casing beneath the motor.
There's a larger silver capacitor (about the size of an AA battery) and 2 smaller black ones about 1/2" long that are in the motor lines. There's a separate power-in plug, and a separate footpedal plug.
I'm familiar with the old type footpedal which contains simple mechanical variable resistors, but what sort of foot control would work with this setup?
