Hello, helping a friend repair a Genie. He has all new boards in it and it is set to his title. Currently in test mode, only 2 coils fire. The large drop bank is one of the 2 but is is very underpowered and cannot reset the drops. Non cpu controlled coils work.
At this point I can start a game but manually work the kickout. After ball 2 drains it resets to attract mode except the coils stay activated. I found this diode shorting and I am afraid he may have damaged his new board.
Also no sound and the knocker twitches constantly in attract mode just slightly. I am completely ignorant when it comes to Gottlieb sys 1 so any help is greatly appreciated.
