Hi there. My Zip-A-Doo 1970-ish EM pin intermittently does not advance the ball. I cannot seem to narrow down the cause and was hoping for some suggestions. When it does advance, the pin makes a double click sound. I've read that if no score registers then it lets you replay the ball but I have registered scores and sometimes it still does not advance.

This is a Bally pin BTW. I checked the Ball-Index-Relay and it appears to be working right as well. It engages each time that I register a score and it stays engaged.

Any ideas? The tilt assembly on the side of the unit was disabled as well. It is designed so that you put a pinball in it and the ball slides forward and up to cause a tilt. I put a ball in there and simulated a tilt and it seemed to lock up the game. I took the ball back out and decided to tackle that issue separately but thought I would mention it in case the are somehow related.
