[QUOTE="Fred W, post: 536250, member: 3828"] Nice post, Ionbeam. Its good to get all that in one place. This was my understanding of the problem too. Which brings up a few poignant observations: Assuming the Gen1 switch is basically the same affair, why so many fewer (if any) confirmed failures of this same type? Considering they have been around longer one would expect the failure rate to be higher if this was contamination based. But that has not been the case. In reality it appears that many of the 2006 MY failures happened quite early in the bike's life. So either the load on the 2nd gen switches is significantly greater or there is some physical difference between the assemblies that makes the 2nd gen switches less robust. The weep hole seems to allow ingress primarily to the mechanical detent area at the bottom end of the switch assembly. It appears more likely that any contamination of the switch contacts would come from above, perhaps from the lock cylinder area. Perhaps from people lubricating their locks in an attempt at "preventive" maintenance? [/QUOTE]
