I have a williams em grand prix machine that the 100 will not score on any player. What happens is if i hit say the pop bumper which is 100 the chime will ring no score will go up and the 100 relay will pull in and stick on. If i manually pull the 100 relay out it will do the same thing over or manually score 100 and make the end of stroke switch open up it will release the 100 relay. If i hit the side switches that is suppose to score 500 and up bonus. It ups the bonus but does not score. Does anyone know what would make the 100 relay not make any of the score reels score. Is there a score motor switch that helps control that? Thanks

Thanks everyone it was the switch on the 100 point relay not making. Seems so simple but i racked my brain with everything else but never thought of that. Thanks again.
