My King Pin is working 100%. The 2nd chute is 25 cents and set for 3 plays. The 1st chute is 10 cents for 1 play. I have gone through the schematic and both work correctly. The issue is that the 10 cents subtract 1 play (25 cents adds 3 plays).
If there are no credits and a dime is used, the game starts and the zero credit stays zero. But, if there are credits and a dime in inserted, the credit decrease by one and the game starts -- but there was credits already available. Thus the player loses one credit; the dime is a waste of one credit if there are credits already.
Is this the design? And why?
