Vending Machines

[MIPS]

Because the evaporator assembly and piping has couplers I think it will be easier to find a suitable substitute, plus god knows how many hours this thing had on it before it was unplugged. From what I gather so long as I can match up the tonnage on the replacement compressor and condenser set I should be okay.

Given that it's a commercial unit parts shouldn't be too hard to find. What do you plan to do about the R12?

The modern variant for R12 is R134A.

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.

The harness is for the most part color coded so there is a lot that I can piece together but its still a lot of effort. The diagram would at least verify the connections, which I would like as I've still not found something like an isolation or step down transformer. I am starting to wonder if this thing is ACTUALLY 120v in both input AND signalling. Terrifying. Not even 24v AC?

Also yes the two fuses are ye ol screw-in type. One for either side of the AC input and rated for 15 amps. I could keep them in there but I've been holding onto a few of the mini breakers for years now and this would be a great time to use them.
