Got the Argentine all cleaned up and mostly working. Still have a couple issues I could use some input on if anyone has any ideas. Fortunately they aren't show stoppers.
1. The coin slide lockout coil does not pull in when credits are on the game or when it's in Free Play mode. In Free Play mode, the coil will lock in if I close the switch associated with the coil, but that's the only time. Closing that switch in Regular mode, even with credits on the game, won't power that coil.
2. The Credit Takeoff circuit activated by the bar on the bottom of the game doesn't work. Pushing on the takeoff bar simply drops out the lock relay, de-powering all the solenoids.
3. The 4 purple bumpers across the middle don't score, they only cycle playfield features. This may not be a problem - I'm just not sure as I can't find anything that says if they should or should not score. I just have a feeling they should but can't find anything wrong with them. The bumpers just have one copper spike on the skirt and a carbon ring on the playfield, and those are obviously working since the feature stepper cycles.
If anyone has any clues on any of that, I'd love to hear them. Also, if anyone has a 1940 vintage game and could snap a photo of the coin door and takeoff switch plate, that would be helpful.
