OK - in switch edges and single switch test, 82 (playfield glass) works fine. I left it on single switch and lifted the playfield, wriggled wires, and it always stayed closed.
The unused switch above it (81) says it is open, however the noise it made sounded like it should be closed. When you moved to a switch that is closed, or close a switch, the machine makes a different noise - and it makes this every time i got to 81, although the matrix display shows it as open. Both 81 and 82 have an "(A)" displayed in the single switch test as well - i did not see that in any other switches in the column - does this mean anything???
I also noticed that when i press 88 (mini pf right door exit), that it actuates 78 (lite lock button on mini pf).
