Quoted from jedi42:If one of those was the culprit, nothing would work, would it? I can start a game, use the flippers, score (albeit only the kick out hole works on the playfield) and the game ends when I drain all the balls.
Bonzo is correct. On most WMS EM's, the tilt relay has a switch that powers playfield illumination and another switch that gives power to the playfield switches. The kick out hole and flippers are on a separate circuit. So check the tilt relay.
