Steve, George doesn't appear interested.
I did locate the current company, different name, who hasn't manufactured these units for so long the tech I spoke with had never seen one. He's been with the company 14 years.
I had to scan the wiring diagram for him.
Not a double capacitor, my first guess about how to hook it up was correct. Seems the compressor died a natural death, without ever doing any work.
Thank you for the effort.
