After time spent tracking wires and trying to read schematics I can't get this figured out (the schematics make no sense to me at all). Game boots, lights, music, and most of the playfield appears to be working. I still cannot get the 3 playfield kickers to work. They work during the solenoid test but they are not getting the signal to fire when the ball goes into the slot. I replaced the diode on the diode board that read bad on the meter but no change. I cannot trace the switch wire back to the control board. The "extra ball" kicker fires as soon as the ball enters the slot and kicks the ball out but the playfield goes dead during this time. Can someone lead me to the next checkpoint? Thanks.
