I have a Gotleib system 1 Solar Ride. It is havings some issues. It has a new NIump MPU board. Power supplies are all ok. When I first turn it on it now shows 55 credits. Thats weird. Game over light is flashing. The two outhole kickers kick once each.
When I press start button credits go to 54 and ball goes to 1. The game over relay never pulls in. The game over light continues to blink. The player 3 display comes on and displays the number 2.
Any help would be appreciated.
