It's really hard to tell. It it can range from 5.25 to 6.75. I somtimes have had to just see how it behaves. If I get a good warm float chamber on initial cool down, and an intermittently opening float when it's stabilized then I know I close.

I added 6 more oz of so2 on the 16th. I have ran this unit every night for about 1 1/2 hours. The extra so2 raised the watts some. It still starts out at around 200 and drops to 140 watts when the pig is nice and frosty in a 60f ambeint. 70f ambeiant keeps it at 150 watts at the lowest. Unit is still siting in open air. She starts right up every time and runs quite. So far it does not make the hissing noise as much, even less when the ambient was higher.

Is there a silica gel liquid line dryer available?

Is there a silica gel liquid line dryer available? Not sure about that. Don't think they are very common now a days. Never tried to find one though.

Well I put the control back on this unit knowing the start resistor was missing only to find the overload heater was gone also. I put a modern overload on for now and tried to make a start resistor that didn't work so I put a start cap on it for now and it starts right up. Also found out this unit is live! 120 volts from the cabinet to ground.Leads to the compressor have only 5.55K ohms to the shell. I am only running it because it is plugged into a ground fault outlet. It may soon die unless it is the wiring rather than the windings. It I touch a grounded wire to it the gfci trips instantly. I think this one is almost cooked from being overheated too many times when it was stalled. If I grounded it and plugged it into a standard outlet it may fry the windings.

Sounds like a candidate for an isolating transformer, assuming it's not a case of insulation breakdown external to the compressor.

Whoa! I'm sure you'll iron it out.

Whoa! I'm sure you'll iron it out. I am really hoping its just the wiring. It has been running sense last night and is just purring along when it runs. It is making my 32 DR 134A conversion sound a bit noisy. It is hard to believe it was so sized at one point.

Just a matter of sleuthing and deduction really. You already did what 90% of the appliance collecting world thought impossible by freeing up a seized motor! Electrical will be tricky but, you've already got it running, just have to "tweak it" home. By the way, who's the member that rebuilds those control boxes like new? I forget his name but, he does amazing work. May pick his brain for any parts missing in your control box.

I am hoping the terminals are carboned up inside the compressor base like Travis's DR-3 were. If so there is a slight chance that the supco88 and filter drier I added may clean them in time. That's probably just wish full thinking though. So far it has run for 1&1/2 days and the voltage to the shell when it is running is now only 110 volts even though the resistance is down to 4.3K ohms. It goes back up to 120 volts to shell when off. Will be interesting to see what happens over time.
As for the missing parts Travis may still have the parts that are missing somewhere, I know he has the resistor still if he has found were it was put. If so I will get them eventually.

Why would it have 120v to shell when not running if it's the compressor? That sounds like something before the compressor, no?
Unless of course it goes away if you flip the plug over.

That's a good point. I always flip the plug over to reverse polarity as a force of habit. Sometimes that's all it takes to eliminate the live cabinet.

It doesn't help to flip the plug I tried it. It doesn't make sense to me yet. Even if its the wires to going to the compressor I thought flipping the plug should have changed it.

Ok I must have flipped the plug when it was running. I tried it when it was off and the voltage is gone as should be. Until its starts again anyway.
