Check the battery for 12.5+VDC (12.0 is not enough).
Top it off with a battery charger. A real charger. The battery maintainers are notorious for screwing you over, killing batteries if left on 100%, and take 4+ days to charge a battery thats down.
Low voltage after a long ride is a inop or intermittent charging system. You should have 13.5-14.7 VDC while running. Less than that and you have a bad Voltage Regulator, bad stator, or bad wiring.
Check the battery for +9.6VDC while cranking the engine over. Less than that is a weak battery, starter issue, or a wiring issue.
Check the ground straps, especially where the battery ground attaches to the seat rail. You need to remove it, clean it and re-torque.
FYI the neutral switch is a single wire sensor just behind and in front of the engine drive pulley, ground that wire and if the wiring is OK the green dash light will turn on. Got a light?, get a sensor (they can also be removed and successfully cleaned). Got no light? check wiring.
