i dont think any of those errors is causing your idol problem ( i dont know much though) to me it looks like one of your optos in subway/idol isnt working and not seeing ball, hence the ball search. test those optos.

looks like idol optos are working and it looks like subway enter opto is registering because it went to jackpot mode when you put ball in, so i would guess the opto farther down subway or the opto in front of idol isnt working(the one on the flat spot before ball goes into idol) when you switch edge test do those 2 optos register?

not there...as the ball goes into subway, it will roll to end of subway, is that opto working? after that it will kick up to a flat spot with a opto right in front of idol, is that opto working? switch edges, test em.

switch edge test...block opto in front of idol, you can see it if you look behind idol, its not in subway. working? if its working then lift pf and use something and try to block optos at end of subway to see if they work, if i remember they can be hard to get to.

just put it on coil test and pop ball out. so if subways are working what about opto before idol on top of pf? you still havent checked that one.
