My advice if I was to replace a voltage regulator is to buy the electronic model available from Zeftronics. I've never heard of someone not happy with theirs. http://www.aircraftspruce.com/catalog/e ... icsreg.php

I am looking for references to finding to correct replacement. (1949 170A, 145-2, original style generator). One guy wants to install a Delco from the auto store, saying it is the same thing without the FAA sticker. I want to install the correct one.

If you go to toward the bottom of the Spruce page linked above they do have the Zeftronics G1200N (p/n07-00617) listed for $140.

But, just for a 'heads-up', grounding seems to be the root of most electrical problems. Our planes are 50+ years old. It's not a bad idea to spend a little time cleaning the grounding contact areas.
Just my experience!

And also Remember, the author of that manual is an idiot. "The single most overlooked solution to generator/regulator problems is lack of proper polarization, followed by improper grounds." ... is not a single issue, but TWO issues.
