Great info and photo.
"Aviation version" scares me since the square-back alternator in my 1982 Aries used to melt those 3 positive side diodes that hang in space every year, like clock-work. When it stopped charging, I knew to look in the square hole to find those 3 diodes gone. I got good at splitting the case open underneath the AC compressor, so I didn't have to remove that. I would buy just the diode pack at an auto-electric shop, and the guy there said my experience was typical. I think they kept the diode packs at the front counter, like a pharmacy I worked at in the 70's did w/ Valium bottles for housewives. By cutting cooling slots in the diode bracket I was able to get 2 years out of them. The 3 negative diodes get more cooling since their bracket bolts to the case. I suspect the problem was the alternator didn't get enough air flow in that transverse engine. An aircraft engine should have plenty of airflow, and I think they still use magneto spark, so the engine doesn't require the battery once aloft. Still, I would prefer a Denso in an aircraft.
