Test score relays by hand
Steps
- On Williams and Bally, switch the game on and push each score relay in by hand; its reel should step.
- In game-over mode a reel going from 9 to 0 will not carry; during a game it should step the next reel too.
- On Gottlieb the score relays only work during a game, so the game has to start first.
- Step each reel to 9 and pulse its relay again: if the next reel does not move, clean or adjust that reel's nine switch.
