After 2 years of restoration, my 1947 Chicago Coin Gold ball is nearly finished. Everything is working (I think) except that it will not register a credit when i initially slide in the coin slide. Otherwise the initial boot up is fine, and normal play is possible when I manually put on a credit. I can't seem to figure out this last problem, so seeking advice from you experts. Of course, no schematic is available for this vintage machine.
If I manually score high enough for free plays, they are added just fine -- so I know that the credit solenoid and stepper are fine.
This machine has had the clockwork switch removed and bypassed.
The coin slide mechanism is very elaborate on this machine, Rube Goldberg to say the least. There is one stacked leaf switch and one "slide-over, lift closed back" leaf switch that I would suspect would be the ones to register the credit, but they all seem fine, cleaned and aligned. See the pictures below.
It even "magically" (thanks to magnets on L-shaped pivot switches) "knows" to score double on the "gold ball", which is non-ferrous.
Would love to finish off this beast, install the glass, add it to the collection and move on ...
Anybody got any ideas for why I don't get that initial credit registered upon sliding in the nickel?
