I have a Bernina Nova 900 and the pedal stopped working. Upon inspection the carbon pins were broken, just installed new pins and still not working. I opened the plug and all the connections are intact. I will order your 3D printed plug if I can troubleshoot the pedal. I used a multimeter and tested the voltage with it plugged in at the plug, the microswitch goes from around 4.5 V to 0.00V when the pedal is activated. The variable resistor is 0.0V and when activated jumps to about 3V and then drops to around 1.5V. Any suggestions on what I'm overlooking?
Hey, thanks for the video. Any chance you would know where I can get a new variable resistor?
Are the resistor broken or do you need the carbon pins?
@@sewrepair carbon pins are intact. I performed a resistance test on the resistor itself, as you showed in the video, and there’s no resistance.

Check the variable resistor and the micro switch with measuring the resistance (ohm), not voltage. The voltages do not tell me much, sorry.
