Working on a Williams Cherokee shuffle alley. The Game Selection button would not work at the start of a new game. Tracing the circuit from the Game Selection S.U.coil F-26 950/250 at C-9 on the schematics back to the Frame Control disc at D-9. The Game Selection S.U fires at all jumper location in the circuit until I get to the Orange wire on the Frame Control disc. The fingers on the Frame Control disc are per the manual drawing in the correct positions at the start of a game as far as I can tell. If I move the Frame Control S.U. one position the fingers on the unit now line up the rivets for the BR-O wire and the O wire of the disc and the Game Selection Button works as it should. Pushing the Frame Control Reset Coil causes the fingers to move back to the start position as shown in the manual. Should another operation at the start of a new game put the fingers in the location of rivets BR-O and O? Hope this make sense?
