[QUOTE="ionbeam, post: 344778, member: 277"] Power for the neutral light comes from the windshield motor drive connector. The drive assembly gets power from the unswitched backup fuse and also gets switched ignition power from the motor drive fuse. The motor drive power goes directly to the neutral lamp in the meter assembly via a Br/R wire. The ground side of the neutral light goes to the starter enable diode assembly via a light green wire. The diode gets grounded through the neutral switch via a light blue wire. The diode must be grounded for the neutral lamp to illuminate. The neutral switch diode sets one of the two conditions that must be met before the starter circuit is allowed to work. If the starter circuit always works with the side stand down and the clutch lever fully released the problem can't be the neutral switch or the diode assembly. This sends you to check the connector at the meter assembly and the connectors at the windshield motor drive unit. If there is stable +12V at the meter assembly’s Br/R wire the problem has to be the meter assembly, the connector at the diode assembly or a damaged light green wire. :dribble: [/QUOTE]
