Newly purchased grand lizard. Problem started after bringing game home. Problem intermittent. Ok typically what happens when I press the start button game will not start. What happens is two coils fire, the one that ejects the locked ball for multiball and the other is the center where the ball goes when it is lost. So typically what is happening is that I can press the start button many many times but all I get is the two coils that fire and nothing. Game will not start. If I reach underneath the playfield and hold down the micro switch lever that activates that center coil (the one that kicks the ball up into the trough after the ball is lost) I can get the game to start and the first ball is ejected into the shooter lane. OK so I can play the first ball and 9 times out of ten when the first ball is lost and drops down into the bottom the ball gets kicked up into the trough and then nothing happens. Its as if the game hasn't recognized that the ball was lost and obviously ball two does not get ejected into the shooter lane. I did recently change the batteries and I did unplug and re connect all the plugs to the power supply. My game also has only 3 balls. Don't know if a GL requires more. Im not sure if this is an issue with the micro switches that make up the whole bottom ball trough assembly or the board. I did run the diagnostics before I gave up for the night and nothing seemed to come up. Any help would seriously be appreciated.
