I have fully restored a Home Run game except for one item. The fireworks over the stadium are on when the game powers up but not during play. I was thinking they came on for a home run, but apparently not. I think I traced the black/blue wire that feeds the two lights back to the 10,000 score reels, and figured the fireworks activated at 100,000 points. I cleaned the traces inside the score reel but that didn't help. No loose wires at the reel. Any suggestions, and can anyone with the machine tell me what triggers the fireworks? Thanks.
