Really need some help with my bike as it won't start. Whenn you switch the ignition on the neutral light is lit, which is fine as the bike is in neutral. When you pull the clutch and hit the start button i get nothing, the bike doesn't turn over.....just silence. I have replaced the starter solenoid, start stop relay and right hand switch gear to no avail. Today i replaced the battery again to no avail. I have found that the diode that is just below the seat doesn't provide continuity in either direction. I have proved the clutch switch is ok but still i get nothing. Would the diode stop the bike from starting if it was faulty? Any help would be appreciated as i am going off my heid with this problem Many thanks Baz
