I am having a sporadic problem with my IJ. When you knock down the targets and lock a ball in the idol, occasionally the ball will enter the lock hole behind the targets and nothing will happen. It doesnt proceed to the idol to be kicked up for locking. The game just sits there. When I lift up the playfield of course the ball is visible in the subway area under the lock hole in the center, but I am sure its gravity because when you look when the playfield is down, you see nothing. I assume that the ball is to proceed to the next opto which tells the machine that it needs to be sent to the Idol and this must be where its just sitting there.

I have cleaned all the optos I see, but I wanted to see if anyone else has had this issue and perhaps another remedy. I can take the subway apart again and clean the optos or change them out. Sure would like to know if thats where the issue is though.

Any thoughts?

I didnt because it does work 80% of the time. So I assumed it did work. I was thinking maybe there was something blocking ball from getting to the opto ( not sure what the first opto is called that send it further down to the solenoid that pushes it up to the idol). Perhaps I need to wait for a ball to not register, then go into test mode and see if that opto switch is till open or closed.

Thats my problem. I cant see the ball sitting in the subway because when you raise the subway, the ball will roll back to the left side of the subway under the center hole. There is no way to evaluate actually whats happening under the playfield
