Put the game in switch test and make sure the rollover switches are properly registering. A bad or missing cap or diode usually causes the switch not to work at all but if you have 3 switches on the same strobe not working it's probably a problem with the row or column in the matrix. Loose pn on the MPU is typically the culprate.
Exactly which switches are they?
So those 3 shooter lane switches, #02, are all wired together and work as 1 switch Most likely only one cap and diode are present. with the game in switch test it should flash 02 when any of those 3 top rollovers are closed.
As for the square 02 box in the shooter lane. Square boxes designate coils and coil #2 is the knocker.
