Just noted you are in Florida.....what is Winter?
It is good to sometimes review things and come at it again at a later time. One last comment, if the BCC has already closed the interconnect relay and you operate the emergency switch to manually close it.....of course you wont hear it operate. I am still suspecting bad contacts (even on a new relay) or something wrong on the control board that operates the interconnect relay (assuming all other connections are clean and tight). You want to hope it is "not" a cct board replacement. Enjoy your Thanksgiving holiday.
