Quoted from Nokoro:

I haven’t replaced the caps. But whenever I’ve had a cap problem in the past it has manifested itself differently. No switches register closed in switch test mode which has typically happened to me in the past with a bad cap. Do you really think a cap would cause these symptoms with the rectangles?

Since somebody else has worked on this game, I would verify their work, especially polarity of the diodes. Eliminate the coin door as a potential problem. Start the game and unplug the coin door 24 pin connector. Of course you won't be able to go into self test but you can manually trigger some switches.

Quoted from Nokoro:

Maybe I'll try that with the old switch when I swap it out just to have a spare. Do you need to use a particular type of paper for the insulation or would something like construction paper work?

good catch! https://www.pinrestore.com/Supplies.html
