I've finally found some time to get back to working on my Big Time. I suspect I've got some problems with the shutter motor cam 5 switches. While inspecting them I came across what appears to be an "extra" wire in the bundle for switch stack 6. It looks like it was partially stripped at some point in its life but for the life of me I can't find the other end of this wire. Am I really just discovering some unused wire in the switch stack 6 bundle?
