I just got a newly purchased 1977 Williams Big Deal set up and through pure dumb luck have not set it on fire (yet) despite my best efforts (who knew you actually have to line up the pins up when putting wiring connectors back in place?). I have replaced one coil so all the reels now will reset back to zero, all the pretty lamps glow again and it seems to be working except it will not index back to Player 1 from Player 4 in a four player game. All other player modes work fine. 1 to 2 to 3 back to 1, etc..... I start the game, push the credit button and every time I press the credit button the player indicator lamps glow accordingly, except the 4th lamp! I start playing, it indexes to player 2 after a drain, then player 3 after a drain and then player 4 after a drain, but on the next drain it stays stuck in player 4 scoring and the player light stays on the 4th player. I can cut the power and back on again and it will reset back to original conditions when the credit switch is pressed. I could possibly live with this, but the Electrical Engineer in me will not let this happen. I will add a photo of the player index unit later on. Any thoughts? I don't think this game was ever cleaned in it's life. The long chime was almost cut in two from use! It is a great unit on the whole and for $300.00 a steal.
