Model #
The tag inside the fridge says it's a model #DC-7.
On the back of the fridge, there is a metal "chimney" which contains copper tubing which serves as the condenser. There is another tag on the back of this, but I haven't read the "style" number on it. It does say it uses R12 (!#%$%^%$$#) and even says how much, so with a little cleaning I'll hopefully be able to read it.
The bad news is that the main power cord enters the fridge cabinet from the "chimney" and runs inside at a place just below the freezer section. It comes out again and then runs down the inside of the chimney down to the compressor. The chimney was once filled with insulation, but it had largely disintegrated and fallen to the bottom. The resulting high-heat environment cooked the wiring that was inside the chimney.
My neighbor came over and we opened up the access panel on the back of the fridge behind the freezer and looked at the wiring there. All the wiring inside the fridge is just fine. The only wiring I can't see is the wireing that goes from the power distribution block behind the freezer to the thermostat and the wiring between the power block, the switch, and the light. I do know that he light was working.
We made a wiring diagram so I can rewire the fridge (Yes, I plan on putting on a 3-wire grounded power cord and plug.)
With the wiring diagram, I can bypass the thermostat and hard-wire the compressor and hopefully test the motor. If it actually starts to cool, I will be a very very happy historic preservationist. If it does not run or cool, I will not be a happy historic preservationist. If it runs, I will unplug it as soon as I detect cold or "unhappy refrigerator noises."
The only lingering question is this: Why are there 3 wires from the compressor and thermostat but only 2 wires in the power cord? What I think we figured out is that there is some sort of a heater at the thermostat (located next to the butter compartment) to keep things from freezing and it gets electricity all the time from the compressor. The thermostat controls the power to run the compressor, but there is a line running more or less though the compressor to provide power for the heater.
Clear as mud?

Sandy, what transmission do you have? The AW70 auto, the M46 manual 4spd + OD, or the M47 manual 5 spd? Also, FCP Groton is another great source for parts.
