I have a Playboy that won't kick the ball into shooter lane, does not work in solenoid test either. Game goes into game and if you manually load ball all works fine, registers end of ball when it enters out hole but won't reload it. On Playboy the U1 3081 only serves one coil (out hole) so replaced it and no change. Changed the 74154 in case that was an issue but still not working. Changed the Tip102 drive transistor and if you ground it, or the coil lug it kicks.
Any ideas, don't normally get stumped on Bally -35 machines but this one is really weird
