In order to get the Brazil upstairs and into my workarea, I had to remove the topper. No big deal, those come off all the time. But in the ancient pre-electronics era when this thing was made (circa 1956) they didn't have modern connectors.
So what did they do?
They used an ancient knife-connector style of thing. The problem is that the "knives" fit in multiple connectors.
I searched desperately for some method other than the "try it and see if smoke comes out" method. Fortunately the previous owner was smart enough to put a dot of colored paint on each connector - you can see the yellow dot easily on the top of the leftmost connector.
Then it was simply a matter of checking each "knife" and matching up the colors!
As a side benefit of this work. The lights now have come on, so apparently part of my problem was just corrosion on the connectors!
