Hi Ted.It's possible that the clutch switch isn't earthing. I think the diode is to stop the neutral light coming on when the bike is in gear with the clutch pulled in and the starter pressed.
Usually one near the coils.
Not wishing to change the thread...it is related to the diode assembly, was there a part number for the rubber boot that supports the 2-way connector and diode? as image Handy item, as it also has a slot to clip onto the bike frame.
Wherever you fit that green earth terminal dont forget to remove the new paint/powdercoat so it touches frame metal
