2003 V-Star Classic. Occasionally, after a ride, I am unable to restart the bike. When the ignition key is turned, the bike is completely dead...no lights, nothing! The battery is new and all fuses are O.K! I wait 15-20 minutes until the bike cools off and the bike starts perfectly. In looking at the wiring diagram, the ignition switch could be a problem? Has anyone heard of a temperature related problem with the Yamaha ignition switch? Or am I missing some other issue?
