OK,
2 things activated the steper thing under playfield(bonus counter up 4 step then reset back to start) I cleaned it steps good the 2 switches on it are open but on the 5000 bonus step they close.They are clean and close tight.
The other thing activted in (advance bonus relay) it has 7 switches 5 normally open and 2 closed,it seems to work.I mean when I move it by hand it opens closed ones and closes opened ones(switches)

The bonus goes up 1000 points at a time..1000,2000,3000,4000 and 5000 these are shown with light sockets in the playfield
