I am working on a Singer motor with the terminal connections as part of and under the motor. There are a lot of wires going in and I am not sure what I can do for strain relief that will FIT inside this box. There were originally 2 disks made of fiberboard with a crooked staple worked around them somehow. It is completely baffling how it goes back together.

Here are pics to show what I am working with.

UL knot.

I've fiddled with the clips and they were just too aggravating

Christy,

You don't sposta take the clippies apart. The end that does not pass through the fiber just clips over the divot on the other part. I take very good care of those cos they do work.

And although Jon is right about the underwriters knots I've not been able to get them small enough to fit in the bottom of those motors.

If you want I think I have an assembled clip I can take some close ups of for you.

UL knots are tight fit but does work or else I'd have several dozen of this style motors laying around unwired. I would like to learn a new trick though.

I have an enlarged photo of the UL knot on my work bench along with an old one from a machine I rewired. I can do them, but I can't get them small or to stay where I want them. I keep trying though.

Hi Joe,

If you can get those funky clips to work I wouldn't bother. They always fall apart on me and I figured they were for one time use. I'm more interested in seeing how to reuse them properly and the OP. If the clips arn't available I've had success with 18-2 SPT2 black wire, not the cheap 6' extension cords from Walmart. Bit of a squeeze but it can be done.

There is no way for me to get an underwriters knot in there. I struggled with the clips for awhile but that was no use. I eventually went with zip ties. They weren't hard to put in and I think they'll work.

Creative idea but I'd stick with tried and true when it comes to electrical repair especially if the machine might go to someone else. I'd search for more info on getting some clips if the UL knot won't work IMHO. Good Luck.

I've seen a lot of zip ties in other newer appliance electrical systems. I did not think of the ties but they will work. They won't rust, won't chemically interact with the wires so I see a good idea there.

I have no source for the OEM clips. The ones I have used came from the motor they were on. The extras came from a busted motor I took apart. You do have to be careful when you unlatch them. Other than the 90º angle on the one end there is nothing holding the pieces together.

Ah zip ties. Will add some of the very small ones to the motor repair kit.
