Correct, the mast bearing wire is connected to a wire that runs from under the dash to the Switch terminal on the horn relay. I disconnected at the location under the dash and made sure that neither end was touching metal of any sort - and to my delight, there was no clicking/moaning/blaring of any kind when I put the negative battery cable back on! I also checked the battery voltage at the battery posts and confirmed there was no drain occurring. So tomorrow, I will run continuity test by reconnecting that wire under the dash (effectively again grounding that wire), after disconnecting the wire from the Switch terminal of the horn relay. If confirmed, I'll see if I have time to pull that mast bearing back out and see where it may be contacting the inside of the column tube. Thank you again bartamos for all the help!
