Ok,been playing around with it ,as long as I have reset the AX relay it will shoot the ball out, drain and will eject the next two no problems,pop bumpers and slingshots are working and the drop targets,altough they don`t reset properly,one target is getting stuck and if I pull it up it`s ok,after the third ball is out and drained the score motor keeps running,all four score reels are rolling over on player one,I haven`t replaced the burnt coil yet so I am hoping that might fix some of the problems 
Nino,the ball return seems to be working..
Typical of an EM that has not been played for a while - each time you play it, it seems to sort itself out. Don't be surprised if it works by tomorrow for no reason !
You still have to manually press the AX Reset. Is this at the end of ONLY the first ball ? Thereafter it works ok ?
The "third ball" problem could be as simple as the game is jumpered for a 3 ball game, not a 5 ball game. You can check this jumper located in the head.
If it is set to a 3 ball game - then we need to look at the "Game Over" relay"
