Whenever I rewire components, the Ground *always* stays a bit longer than the other wires. So if they come loose, you still have a working fuseto ground out. That's especially important around drilling machines and everything on construction sites that sometimes gets hanged on the cordline...
Thanks for the video. Just in time for me! I'm about to clean my knee control Bernina Record 730 with degreaser and I want to remove the motor. (Although I have done this process with Singer sewing machines with the motor still installed and no problems, I'll proceed with a little more caution with the Bernina.)
I have gifted a made for US, 120 volt Bernina Record 530-2 with knee controller. Is it necessary to replace the capacitor and resistor? I’m a beginner with Bernina Machines and learning. Thanks
Yes potentially you have a capacitor that is 50+ years old the life expectancy of this component is approximately 20 years and so for the sake of protecting the motor and the potential fire risk of paper foil capacitors I would suggest best practice is to replace it
Thanks for this, I am hoping to bring a first year 730 back to life with this.
Best of luck!

Is the function of capacitor for speed control as I've also found a capacitor and 1mega ohm resistor in the foot/knee switch
