Ok I bought a Comet and now that it’s set up I’m discovering some switchs are not switching as it were. I’m new to this and looking for some guidance here. The game is unplayable because the eject saucer in the cycle jump shot doesn’t trigger and the outhole when you drain doesn’t trigger. So if you identify a bad switch do you replace it? Switch test says not working what’s the next step? Then- and I am just learning what a switch matrix is- what is this sudoku puzzle telling me? I have column 4 with 6/8 down, and 2 rows with 2 down. Anyone able to point me in the right direction here would be a friend indeed
