So I had my Aztec running great and then a few problems crept up. The first one was that I couldn’t start a new game. After doing some trouble shooting it seems like the index switch 1c needed to be cleaned. Once I got that fixed, now when I play a game and the ball drains, nothing happens at all. If I hit the relays inside manually I can get it to reset and cycle through the game. The switch that is activated when the ball drains (believe it is the outhole switch) is clean and making contact. Anyone have an idea of where to start. See attached schematic.
Thanks!
Chris

Thanks for pointing me in the correct direction……. I will take a look at this.

Cleaned outhole relay switches and then the extra ball relay switch “c” because the Ball index relay was not pulling in. Now it works great!!
