Does anyone have an understanding about these bikes I currently have a headlight issue where all the lights work except full beam I understand that the lighting circuit for these bike runs off of the stator as I have recently replaced the stator regulator/rectifier as well as starter relay i have checked sub fuse a/b and there fine not blown or anything i have also checked the bulb and replaced it incase the filament was blown it isn't the left handle bar switch is working as tested with a multimeter unless i have a break in a wire somewhere I'm kind of stumped as to what could be wrong

edit now solved it turned out to be the multi block for the left handle bar switch where it plugs into the main loom it had corroded due to the salt on the roads

any help or advise is much appreciated
