Hi, I had the game stop working about a month ago. Didn't get around to looking at it until today. The GI comes on the playfield and backglass. The speaker makes a noise similar to the noise that the backglass spinner on Black Hole makes, just using that as a description.
I see a blue wire from the bottom that looks like a ground wire unattached, see photo.
Can anyone tell me where that attaches? Probably a long shot but the fittest step. Thanks
