Upper right flipper on my Addams is strong, but flickers when you try to hold it out. I did a rebuild kit on it, and same issue. I also looked at the lower right flipper's EOS switch, and when I manually hold it down, it still flickers.
Thinking it must be a power interrupt somewhere, but am struggling to find it. Have done the basic checking of connections in the back box.
Any help on common places to look would be appreciated!
