Total newbie here, but having fun and learning. With the help of old posts on Pinside I have got this thing working decently but now getting into "its working, but is it working correctly?"
I can't figure out the drum wheel in the lower right of the back box (circled in the picture). The wheel is marked from 1 to 37 but the pins that contact the relay switches seem to limit it to much less than the full 37. Is this a credit counter or something? It has 2 solenoids on it. The little window that it shows through the glass has no label as to what it is. The wheel does change positions during the game, but what is the limit of travel? And if it might have gotten turned on the shaft? Or is it keyed into place?
Thanks for any help.
