Ahh, OK....I understand the kicker hole your're talking about.  Gee, its really hidden up there!

I will test for you tomorrow, but MY understanding of it is that it should kick the ball out - unless the lock sequence is running ie multiball pending etc...I think the other hole half way up on the far left (middle pf) is the same....You should be able to manually activate the switch, to ensure the kicker is working.  If it is then I would suggest that everything is a-ok.
