Something is up with my ebd. When the ball drains the ball trough will not eject. I think it is somehow connected to the one ball target. When i depress the ball lever in the trough the one ball registers and drops...im guessing a bad ground somewhere? Any ideas?

You mean in the solenoid that ejects the ball?

Thanks for the input. I changed it out the existing led for an incandescent bulb (though, I think it may be burnt out) I also noticed that the wiring for the socket wasn't soldered and was just wrapped around the post so I soldered it. re-seated the connector on the board, reflowed the diode on the #1 drop target too...not sure which it was that fixed it but I played 11 of 12 games and had no issues. Thanks for the help!
