Apparently there is some secret HD memo somewhere that says if you have any electrical issues, just eliminate all circuit breakers and hot wire everything straight to the battery. I have worked on two of these now and they are both wired straight to the battery.. no fuses.. no circuit breakers.. no fusible link. Nuthin. Oh except for the turn signals and and warning lights.. those they just left disconnected.
Are Sporster fires a common thing? If not I am very surprised.
