Having a problem with my Dipsy Doodle. When you press the start button, a game will start and the ball count resets to ball 1 during the startup. It will then switch to bail 2 and eject the ball. You can play a game and it appears to play fine. When you start another game the same thing happens.

I've been looking at the schematics and I'm decent at reading them, but I'm unable to figure out what could cause the ball count to jump from ball 1 to ball 2 during startup.

I've attached a photo of some of the schematics.
Thank you

No points scored.

pinballdaveh It closes, then quickly opens and closes again.

The tilt wiring and contacts are all good.

The score stays at zero. All the bells work and I don't hear any bells at the start of the game.

I got it working. One contact on the ball index relay was staying closed when I should have been opening. I believe it's the ball index relay wire going to the outhole relay. Thank you again for the suggestions, it helped me narrow it down.
