I bought a project Strato-flite a few weeks ago. The game had been up and running, but with problems. The game would start, and play the first ball, but never advance. I found lots of help for what could be causing the problem. The first was a gummed player stepper in the back box. I cleaned and got that working. That didn't have an effect on advancing the ball though. I checked the action on the ball stepper. It seemed okay. One of the fingers was bent off the copper so I did my best to repair that. Then I checked over all the relays. They seemed okay. Adjusted a couple but very minor adjustments. Then I remember something happening on the coin door where suddenly the game seemed to be endlessly producing credits. I checked all the contacts on the coin mech and again made some adjustments and the endless credits seemed to stop. That's around the last time I remember the game behaving like a game. I may have cleaned the jones plugs somewhere in there too, and removed and inspect the fuses.
Here is where it gets weird.
When you power up my game now, everything produces a credit.
You don't have to start the game. Press a flipper. Credit. Touch a target. Credit.
I've checked, and the game over relay seems to be working correctly.
However there is still power going to the flippers and if I touch anything that scores points on the table. A credit.
If I start the game, the game goes through it's proper start-up. The relays fire. The steppers reset. The ball is ejected. However no playfield lights come on, and nothing scores. Everything just activates a credit +1.
I've been checking relays, messing with the credit reel, examining the coin door. I cannot figure out what I've done.
Does this sound familiar to anyone? Anyone want to give a noob a helping hand diagnosing this weirdness?
Thank you for anything
