I have a few ideas on what to do with the machine but I'm keeping those secret for now. In the meantime however I have been overly unsuccessful finding the service documentation. I still need a wiring diagram.
I have now inquired through all the major sources for vending machine parts, supplies and service and either they don't support this machine due to age, they don't respond to my email or in one case, it blocked my emails because it looked like spam...
I wonder if you would be able to trace the wiring, in the event a diagram is unavailable? It looks pretty rough but may be intact enough to figure out where everything goes.

Also, are those screw-in fuses on the bottom right of the machine? I remember seeing something similar on an electric range - each burner had its own fuse. Must be some kind of Canadian safety regulation.
