it's either the relay itself or a problem in the circuit. either a broken wire or maybe a melted wire.
the signal wire to the starter relay is a yellow/red, the ground from the starter relay goes to the diode in the fusebox, then to ground via the neutral switch.
if you want, try to put 12v on the yellow/red at the starter relay (just use a jumper wire from +12v), if the bike cranks then you have an issue with the power circuit to the start button (headlight circuit)
if the bike doesn't crank, try connecting the green/red at the starter relay to ground. then try to start it normally. if it starts then you have an issue with your diode (or your neutral switch)
if the dash indicates neutral then i doubt it's the neutral switch, so it may be the diode.
