Oh no! Dang, that broken lead is likely going to be the end of that lamp's usefulness. Maybe one of BVH's suggestions will work but I am thinking the same as him in that you won't be able to reliably reattach that lead. We feel your pain.
Good luck to you, I sure hope you find a workable solution!
Nice pics! Now I see how you made the lead work. Do you have anywhere in a rural area to let her rip so you don't have to worry about offending your neighbor?
Those are cool. That's too bad on your electronics problem. Hopefully you will get her up and running again.
