I think it is Nino,but when the ball drains it is not resetting unless I do it manually..

Ok ive been following the thread, but now im getting confused

when the ball drains it is not resetting unless I do it manually

From this - can i gather that you can almost get a game from it? In other words you can score points etc but the game will not reset unless you manually move the AX relay?
 AX relay is triggered by S relay through BX relay, U relay and score motor switch 2C - if this sequence is not correct AX relay will not energise.

 Turn the game off at the wall - manually move the switch stacks so the relays are in contact ( solenoid is pulled in mode) - you can see which relays should be making contact and which shouldnt - put DMM onto OHms mode and test continuity from where the wires are soldered onto the copper leafs, look at these carefully - it can be decieving as the soder joints are staggered - this is where an anologue meter is much better cos you can see the needle sweep. If you have a switch that looks closed but does not have a low reading it is not making contact - similarly if switch looks like its meant to be open but reads low ohms then it needs adjusting - its a finite adjustment thats required
