I am thinking it is something simple, but I am pretty new to this. I have a Williams world cup soccer and none of the solenoids are working. the flippers work but both the pop bumpers and four ball releases don't work... I checked all the fuse and none of them seem to be blown, I played with all the connections and still nothing. I am a little stumped. I know someone is gonna tell me to check something right away and it will probably be it... and I will get go doh!!!
