I have a 77 Puch Maxi-Luxe and the guy that I bought it from,said that the lights and horn worked, before this cable that connects on the left of the handle bars, broke loose. So basically, I have no electric, and this cable that is not attached to the screw thing that is located next to the left brake lever. Can anyone help me? Please! I need to get the brake light working before I can ride on the street.
