After umpteen months, when I switch on the engine, in neutral gear, the neutral diode would not light up unless the key was turned slightly anti-clock. Upon the advice of Roda Radius Garage mechanic, I dipped the key in grease then slot it in and out a few times. This time, every time I switched on the bobber, the neutral diode came on! Once turned on, I stirred the key in a circular motion to give the grease a better spread. I assumed the grease helped remove stubborn grit that blocked contact points built up over time because the grease inside the key slot turned black in colour.
