i left the ignition switch on for 2 hours, and my 2009 Piaggio MP3 500 will not turn over now. There is no current going to the handbrake micro switch. The running lights, horn, signals work, dash lights up. i cannot read enough on the Piaggio Manual Schematic to determine where the micro switch is powered from. Anyone know of a decent electrical schematic, or what might be a likely cause?
