My Indy is giving me an error at the boot of the game about a supposed Single Drop (stand-up target in front of captive ball) switch / coil error.
Mechanically the assembly seems perfect. In solenoid tests coil 3 ("Totem Drop Up" - this is what resets the stand-up target) and coil 16 ("Totem Drop Down" - this is what triggers the target automatically) fire perfectly every time. The target registers correctly in edge switch tests every time. I will mention, in case this might matter, that the opto for the captive ball (behind the drop target) is normally open in the ball's resting position This should also be correct..
Everything seems perfect in tests. However, in game the stand-up target never resets. Literally the only way to get the target to stand up is to do it by hand or by using the solenoid tests and firing the "Totem Drop Up" coil.
Once the target is dropped, every time thereafter during the start of a ball or booting the game, the "Totem Drop Down" coils seem to fire three times in rapid succession (even though the target is already down, and besides, the game is supposed to bring UP the drop target at that point, not the other way around..)
There have been some threads about the error message such as this, but in this case the issue was the error report only, the game seemed to play correctly otherwise:
Given the above thread's conclusions, I will mention that my game is a reimport and has only a single Coin Door Interlock switch (the smaller two-lead one) and is missing the second, bigger switch. This was apparently standard for games built for export.
Any suggestions would be greatly appreciated!!
