Well problem solved but not fixed. After staring at the wiring diagram for a long time and testing continiuity I decided the problem had to be at the ignition switch.
Handlebars off, yoke off. straight away I seen the wire that feeds the sidelight is hanging out of the ignition.
The issue now is that all u really want to do is open that ignition up and resolder the connection but it's all sealed
Anybody know how to open it up, or if not how the hell do I undo those security nuts at the bottom?!
