Firstly thank you for the reply. This part was taken from the right hand side under the killswitch/horn button, it has a brown wire, as well as a yellow/green one coming off it. It is fed into the same wiring loom/rubber sleeve as the throttle cable. It does have a small press-able button on it which i can assume is pressed when the brake lever is engaged which would suggest it is indeed the brake light switch as you said
That said, i did just check the clutch switch as you mention it and it was quite loose/lopsided, i unplugged and replugged so will try that. Upon doing so i noticed the starter motor is still clicking/turning when i push the button so cant be that after all. (flat battery hence the clicking)
I will have to charge the battery and report back, as the starter was constantly engaging it has run the new battery flat.
as a sidenote, my side stand switch has always worked as it should ie will stall if side stand is down and in gear. BUT, it is covered in oil and road grit so will give it clean.
i believe you may have solved my issue but will report back after a charge
and thank you again, truly.
