I've done some searching but can't find the answer to my question and perhaps George or someone else has the data.

My voltage regulator is a Delco Remy with 1119 253E stamped on the frame at the top mounting. What regulator do I have? It's currently regulating a 35A generator but I suspect it's not the correct regulator.

There is a lot of part numbers spread throughout a few post but none answer this question. Later today I'll probably also copy and past as many of those part number here so we can collect the info in one place.

On the Delco-Remy site, it shows 1119253 is replaced by 1119168, which is Regulator,
12 Volt/32-36 Amp, Dual Polarity, 14.1 Vset, Three-Unit Type, A-Circuit, 3-Terminal

This doesn't exactly describe what you have, but it may give you an idea of the amp rating.

Ron I found the Delco Remy site but didn't put my part number in correctly. I did as you did and like you find it is superseded to 1119168. But I couldn't find any more info on that number. How did you do that?

BTW Ron, why do you say the description you have is not what I have. Sounds like exactly what I might have.

Here is more info including Delco and Kelly part numbers I found in Aircraft Spruce catalog.

The description I posted is for 1119168 http://www.motorcityreman.com/deoe1111d61.html

which crosses from 1119253. I was just saying it is not a description of 1119253.

Delco-Remy has the blue prints for both regulators, but no rating data.

More Delco numbers provided by George.

I did a search and found the part numbers for 20 & 35 amp gens...but no 12 amp. Can anyone give me the part number for voltage regulator with a 12 amp generator? Also where to get one?

The original part number (Delco-Remy) was 1118383, but it has been superceded by VR-300-14-20 (same as the 20A unit, formerly known as 1118736.)

For testing purpose only:

Bruce-
Again, the statute of limitations is in effect, but after my voltage regulator blew out one dark night in about 1975, I took it to the local auto supply store, layed it on the counter and told the guy, give me one of these. He promptly brought one out and handed it to me. I asked him what it was for and as he gave me the strangest look, he said, "Cadillac". It was still working in 2006 when I had it replaced with the genuine FAA approved regulator that came with the STC'd alternator kit.

Richard there is no doubt there are a lot of fine working voltage regulators out there. And we have, spread throughout this forum, documented what the numbers of the aircraft variety are. Besides trying to find exactly what I have, the point of this thread was to put all those part numbers in one thread.

Ron the Motorcityreman site, http://www.motorcityreman.com/delco1.html, has a lot of information useful for identifing non aviation regulators.

For archival purpose I compiled a PDF the pertinant information from that site for all the Delco Remy regulators they list that look like an aircraft component. (These are not aircraft parts unless of course you can show one of the part numbers is an aircraft part or crosses to an aircraft part.) I've been told my PDF won't open on some computers. Usually has to do with not having the latest Adobe Reader on the receiving computer. For those that can't open the PDF or who want a Word document here is another option.
