Okay, a ten year old bike... I would check my grounds. If you are like most Harley owners you wash the bike a lot. Even if not the grounds are going to lead to corrosion and create resistance. Back in the day I saw it all the time. If your grounds are all clean without corrosion check your power lead connections for fit and corrosion also. Any other ideas will have to wait until you check these...
