Hello everyone. I recently purchased a 1975 Williams "Little Chief" in decent condition. We got it home and fired it up to find that it was in working order. After playing for an afternoon we were shocked to see that the game had stopped registering score. Score reels reset, score motor runs with game play, and game registers credits and balls. We have tinkered with the score board and the reels will work and reset. It seems as though there is a disconnect between the score motors and the reels. We have gone through and checked fuses and wired connections without finding anything that had come loose or burned out. Any suggestions on what may be the issue?
