Those resistances look very good, and you're correct the lower resistance is the main (run) winding. I bet the Supco relay will make it work correctly.
These projects can indeed be a roller coaster ride! Best of luck with the CA. That's one I haven't got yet. I want to learn about the Methyl Formate system.

Thanks for confirming the wiring and resistances David!
Still learning as I go. Glad I’ve been a good student lol. This GE has become my daily fridge and definitely won’t ever part with it. I’ve had moments where I wish it’d just work and behave it’s self. But on the other hand ive learned so much along the way.
The CA I’m getting is from Herb From what he’s shown and told me. The ca is in great shape! Hoping it’ll be a smoother ride haha. Think the challenge will be getting it from Ohio back to Pa. feeling both exited and little nervous haha

For the CA transportation, just be sure to strap it down well. You putting it on a trailer?

Herb built a crate for the top and already has the top on the crate and ready to roll. Very grateful for him doing that. I’m going with some friends and we are bringing it back in there Tahoe. So hopefully it all goes well. I think I’ve read to many horror story’s on things getting damaged wile putting the top back on. It’s one of the smaller models so hopefully it’ll be easy to manage. Or maybe I’m overthinking things... lol. This will actually be the first monitor top that I have ever seen in person. Hence all my excitement ! I’m also looking forward to seeing the other vintage fridges that Herb has in his collection! It should be a fun trip.

Yes, best of luck! Luck helps, but being careful helps more. I have always used my overhead hoist to remove and install the tops. Never tried any other way. I consider myself relatively strong (diesel mechanic) - but those tops are heavy and delicate! Two or three people at once are never as coordinated as you would think. The mechanical lifting method is the best. Even if you have to hang a come-along from a garage rafter and use it to lift the top, then slide the cabinet under it, and lower it onto the cabinet - that would be better than trying to do it by hand, IMHO.
When I've recovered these fridges, I've always put a ratchet strap around the cabinet and top (to hold it together) and then moved the unit as an assembly. Once it's home, I can use the hoist to remove the top.

Once it's home, I can use the hoist to remove the top. I agree with you. But I don’t have such things at my disposal. But the friend that is going to be helping me move and lift has helped me bring home lots of vintage things in the past. they were extremely heavy. we’ve both gotten good at being very conscientious of our movements. I’m very lucky to have a few friends ( though they don’t have the same love for vintage appliances that I do ) that will go the extra mile and help me out and be very careful. In this case. I think I finally caught there interest when I started to explain that this particular model uses MF for a refrigerant. Lol. The usual glazed over look I usually get turn to a big “?” Lol. That eventually turned to full blown interest.

I got my relay today. Have it installed and the fridge starts right up. Amps are 2.68 Are these relays suppose to feel really hot to the touch ? Like enough that you can’t touch it ? Seems not right to me.

Seems not right to me. Yes sir, the Supco "relay" is actually a thermal timing device more than a relay (with separate control and power circuits). It is a "positive thermal coefficient resistor" to be precise. What that means is, the hotter it gets, the more resistance it has. When it's cold, current flows easily through it. As current flows, it gets warmer. Eventually it reaches a point where the properties of the material in it rapidly gain resistance. Once it gets to this point, it immediately gets very hot, and gets a very high resistance. As long as voltage is applied to it, it will stay hot, and stay high resistance. There are a few milliamps flowing through it (enough to keep it hot but not enough to damage the motor's start winding). It needs to cool back off to a low resistance state before the next start cycle.

Oh ok. I didn’t know how they worked. Once again I’ve learned something new! :-). I just figured it was a smaller version of what the original was. I have to admit that how hot it felt spooked me a bit ! Cause it was to hot to hold or touch.

Thanks for those links ! :-) Here is the relay installed. The wire nuts are temporary until I see that things are going to continue to work right. If all stays well then I’ll solder and heat shrink the connections and make things a bit neater looking. I Have the original overload first in the circuit before the supco relay/overload. It’s the only way that made sense to me to hook it up. As a bonus! ( for me anyway .. lol). The original relay still moves and clicks even though it’s not feeding the start winding anymore. It’s nice to still have that classic start up sound !

That looks very nice, and I'm sure it will work for years! You've got dual safety on there now. This will help prevent such heartbreak as Shane had with his Crosley Shelvador; where it's one relay failed and burned the motor.
