While tracking down non functioning turn signals I discovered a broken turn signal wire inside the control head. I very carefully took it apart right up to where the black "bake light plastic needs to be separated from the circular metal disk with the 3" tube coming off it. When I tried to to separate these two the bakelght Shattered into piesces. I have another partial control head and it just might be possible to do do a repair. Does anyone know if there is a link to rebuilding the control head?
