Early Bally flippers don't use transistors. Check the lower right flipper it should have 2 switches. The one farthest from the coil controls the upper flipper. It should be open until the flipper activates and then it closes activating the upper flipper
Quoted from Pauz21:Just one last question. I put one of those watch battery holders on the mpu board.
It works fine but then it hit me… do I need a diode or is there already a blocking diode in place.
Check pinwiki to see if you need a diode in this application
