i have a space mission game plays one player well but when i try a2 or 3 player it will play a four player game even though the 3 can play light is on the back glass then it gets stuck on player 4 ,the player unit in the back seems fine
but i noticed the player reset relay does not always fire after the last players ball drops wether its 2, 3 or 4 player game
it usually works with one player ok .should it fire after the last players turn is over ?is this controlled by a stack in the switch motor ? or am i wrong and should i be looking elsewhere .the ball count was also gets stuck sometimes,it fires by does not always seem to push enough to advance ball count, will clean it up again and clean the advance selenoid
really could use your help ,and thanks in advance for your help

Thanks will do. I'll let you know how I make out and i agree it is a great game

cleaned up the units you suggested and presto works great.it was the ball unit that was the culprit ,then the ball return didn't always have enough oomph to pop the ball all the way back to shooter lane so i cleaned up that selanoid too with some alcohol and another long standing problem solved .learned a lesson too ,keep it simple ! a good cleaning goes along way ,thanks for the help and steering me on the right track
