I have a Frankenstein that has started to give me an issue. When I flip the right flipper which also activates the top right third flipper. The problem is the top right flipper stays activated when releasing the right flipper button. It eventually goes down but not immediately like it should and occasionally stays up a long time. I did check the leaf switch and cleaned it. Appears to be making contact fine as it should. I am also in the process of ordering and replacing the coil for the upper right flipper hoping that will fix the problem. But is there anything else I should check or any other issue that may be causing it? Anyone else have this issue on msf or any other game with a third flipper. Thanks for the help.

Thanks for the advice. I will check that. My concern is that the coil seems to be staying active. As when the ball goes around and hits the third flipper while it is up, the flipper does not drop down. In your scenario I would assume the ball hitting the flipper would help lower it. In my case, it seems to be still powered.

I checked that and cleaned it to. All looks good with the leaf switch. That's why my other thought is replacing the coil.

No. I can check that too. Thanks.

Fyi. Simple diode came loose. Problem fixed! Thanks.
