Great day! Thanks again to all who responded. HD shop found the problem and it wasn't anything they did. They tested wires from front to back, sometimes getting a break in the circuit, sometimes not (my language, not theirs, ha). Finally, they pulled a group of wires running along the left side of the frame, under the seat. They found two completely chafed wires, which were initially protected from the frame/oil tank by chafing tape (I now have the chafing tape, worn through, as a souvenir).
I apologize for my description being rather non-technical. I am so dang happy to have my bike back! Thanks again to all.
Peace,
Max
