I am having a hard time localizing the problem I am having. The sensor for when the ball drains between the flippers isn’t registering. I have been able to trip the solenoid to kick the ball over when I trigger the outlet relay or the 300 score relay. I can’t find any loose connections. The game otherwise is working well. I have tried to understand the schematics that came with it but honestly don’t understand them. Any insights or assistance would be appreciated. I have attached the pictures of the schematics if that helps.

If the Outhole switch doesn't activate the Outhole relay, Inspect and diagnose this circuit with Alligator clip jumper wires
