Singer 99 Rewire-bypass knee controller
 

I have not been on here in ages and it warms my heart to "see some old faces" https://cdn.quiltingboard.com/images...es/biggrin.png Not that anyone is OLD here, lol! So I have a Singer 99 ca 1934 that actually came with a knee bar, woo hoo! However, the controller inside the bentwood case has some missing items and is not even wired to the motor. I will say here that I am not super savvy on rewiring and so this setup has me a tad confused. Because it has the knee bar and a foot pedal, it makes sense that it is a 3 wire setup coming from the plug. When this is plugged in the light works, motor works as should, and pedal works, and of course the knee bar does not. If I use a two wire plug set up then the motor runs continuously. I know intuitively that it has to do with which wires are connected to each connector. What I don't know is how do I fix this? The friend I am fixing this up for wants a new electronic foot pedal, not the old metal one that came with it (I suspect not original). So, I will need to figure this out and know which wires stay and which one does not. Will I have to remove it from the motor? Any tips and direction most appreciated!

Welcome back. I'm not sure I'm understanding "If I use a two wire plug set up then the motor runs continuously." I think what you want is something like https://www.amazon.com/NGOSEW-Univer.../dp/B071Z4F3DH where if you plug the motor into the outlet marked "motor" then the foot controller controls the motor.

I really don't do electrical wiring. Perhaps someone else would be better to help. It may help if you posted some pictures. QB software changed last year so to post pictures has changed. We like pictures. In order to post pictures on Quilting Board, you will probably need to reduce or compress the picture to a file size that is smaller than 2MB. How to post images can be found at https://www.quiltingboard.com/attach...020-01-17-.pdf
Don't forget to scroll over to the far right to find and click on the "Upload" button.

I have found that only the big red "Reply" button or "Quote" work to give me the paper clip icon to work for adding pictures.

Not quite sure what you are after, but this may help....singer 3 wire diagram - Bing images

By any chance does it have a "Century of Progress" badge as seen at https://www.collectorsweekly.com/sto...of-progress--1 ?

Here is another 1934 that has the 3-pin plug like the wiring that Leon posted. https://www.youtube.com/watch?v=Toznd-XB50s
