If it's reporting optos as bad, check the opto board power (any other fuses blown?)

The game 'knows' when optos are out because they are normally closed switches, that the ball breaks the beam when present. So it can mark those as bad right away. 'Normal' switches (mechanical microswitches or leaf switches) are not marked as closed for a certain # of balls, or if there is more than one switch that logically has to activate before another; if the game sees the second switch but not the first consistently, it will mark the first as bad. (This type of switch is often costed out of a game as the software can logically assume its function)

Optos are normally closed so that column of five boxes shows that all five are reading. Put your finger in front of the optos and see if they change state.

You can also use switch levels test which will scroll through and tell you all the switches the game sees as closed.

Jump test should be without any connectors. That way anything on the playfield can't interfere.
