OT: John T or Jim N, and EE/ac voltage experts

I have been working on repairing an old Sunbeam electric mixer from the 1950s. It has a 2 wire cord and a wax radio suppression capacitor with three leads: one to one power wire, one to the other power wire, and the third to the body of the appliance. The power wires attach to the field coil leads (brushed motor) at the same connection the suppresion capacitor makes. What would you recommend be done during cord replacement and component replacement? should i goto 3 wire or not? should i install a similar suppression capacitor (where do i find one if i should install one?)? Local electric motor repair shop and appliance repair shop have not been able to help with that component or give definite answer on cord. On-line appliance shop (sunbeam authorized and 40 years in business) only can get used capacitors (installing used is scary).

somewhat on topic, the speed control of this mixer has points, condenser (different purpose than aforementioned suppressor), and a ceramic resistor, and a mechanical governor!!! fortunately those components do have modern replacements available. RF interference was pretty bad previously, and the speed control components did test bad. the suppressor was all oil soaked.

Replace the dual paper suppressor capacitor with a couple of 250V ceramics, .01Mfd or so (exact value doesn't matter). Use a three wire cord. Connect the green wire to the frame.

I agree with John, Three wire cords are easy to find Below. Use a strain relief to keep pulling force off of the connections. JimN

I agree with the other fine gents, if I had an appliance that had an outher conductive metallic case (not nowadays, all plastic lol) and I were rewiring it, I would fer sure bond the third green safety equipment ground conductor to the case. That way if a hot shorts to case theres a dedicated low impedance fault curent return path back to the panel to trip the breaker n save a life. Without it theres no trip and the case is sittin there energized at 120 volts so you touch it and may dieeeeeeeeeeeeeeeeeeeeeee. Sounds like a good reason to follow our advice Eh ????

Those lil ceramic capacitors are cheap as dirt, buy a couple n wire them back in cuz that high frequency static noise interference gets shunted out versus radiating n transmitting to your radio n TV......Capacitors loveeeeeeeeee high frequency, it goes right through them like when you go to White Castle n buy a greasy onion filled Slider that slides right through your body lol
