Everything works perfect however every time I add a quarter to the coin door the stepper motor subtracts a game instead of adding a game. Has anyone ever come across this problem? The game allows credits to be added when you win a game or match but for some reason if you add a quarter it takes away a game. I can manually add a game by pushing the plunger of the coil in the rear of the head . Any ideas?
Got the game about 10 years ago and have not touched anything...decided to look at all the bugs and see if they could be corrected...yes the stepper unit was touched before I got it....2 new wires installed...appear correct...ratchet was lubricated...and some fine adjustment with 2 screws was performed.....coin adjustments in door register but I can only see the 2.
