Fixed my issue by tracing wires.
When I had bought this game the GI was not working. Somehow I did not notice this until after I had it home -- amazing what gets overlooked when the excitement of obtaining a new pin kicks in. The old rectifier board looked rough. The GI connectors were burned and the wires had been removed/soldered directly to the pins on the back of the board. A new board from Pinball Resource is now in place:
The new board and repining connectors (everywhere!) fixed my lack of Illumination!
I also made a new light baffle for the eye/pyramid lights on the backbox panel. The original (sitting on/above my new piece in the picture) stuck out far enough that it actually made significant contact with the backglass -- so much that it put pressure on the glass when it was installed. I thought taking the stress of the glass might be a good idea. . . if nothing else it makes me feel better.
Must have played 20? 30? games in the last two or so days. Hard to walk away!
Still have several things on the to do list. Next up will be updating the 5V and High Voltage components on the Solenoid Driver Board.
