I'm not sure I really understand this, but if you're saying that the connectors themselves fell off and you can't reattach them, you don't really need the connectors--the wires can just be wrapped around the posts and will make the connection.
That being said, I have never tried to rewire a knee lever controller. Most of the ones I find with a knee bar are in very sad shape, I have found just one that was in good condition, and I left it alone. The others get converted to HC. It just didn't appear to be a good design.

Ok, next I took the a plate off the motor of the 128 (parts) to see how is was wired. Well, it was a little different but not too much. After doing all this, I discovered that I didn't have to take the cover off the 128 at all. The power cord simply screws into 2 connectors on the right hand side plate. My problem is that I don't a way to take the connectors from the parts machine and attached them to the good machine. When I tried to remove the "plug" the wire just fell apart in my hand and I can't see a way to re-attach the wire.
Should I just give up and take it to my service guy???????
I so wanted to be a "good sewing machine mechanic". :(
