'46 Generator?

[johnshenry]

I have this generator (left) with an "8B" stamped on it. In Bosch codes that would be August 1946. I never really believed that it could be that old. Tonight I compared it to a "10F" (Oct 1950). The housing is identical. But the 8B one is 2600A15, and the later one 2600AL15. Also note the differences in logos and the "Germany" lettering.

Can anyone confirm that the early gens have this lettering/numbers? I suppose it could be for another car, but the bores and openings in it are exactly like the other one, and even if, it is still date coded 8B.

Any thoughts??

Click on the pic, it is big...

What type is left one?Looks like ND 180/6 if i can see it right,then it is not Volkswagen generator.

[johnshenry]

No it is a "RED 130/6" just like the right. Click on the pic to see it full size, you can read it better. ANYONE have an old gen or even pics of one from the 40s??

The wartime beetle, schwimmers and kubels have the RedK 130/6 2600AL15 in the parts list, it would perhaps be strange if 1946 was different without a good reason? I have heard (never looked inside) that there was some winding difference wartime to save copper but I doubt there was much difference in its availability in the immediate post war period either?

John, I don't know if this will help you it may add more questions....
Here is my November 47' Generator. It is marked "REDK 90/6 2200 AL15"
it is same as your supposed 46' unit by not having the script underneath the Bosch word, but thats where similarites end. Mine is also dated below the arrow like later units, not like yours or the 42' unit posted. Not sure why kine is 90/6 and 2200 compared to 1xx/6 and 2600. Note: My unit also has its original voltage regulator which is also dated 47.

Do you know what the 90/6/2200 on your generator means? It stands for an output of 90 Watts/at 6 Volts/at 2200 RPM (Revs per minute). I believe this is spec is for 1947 only. Would I put it on my 47? No, not if I was going to actually use the car! Why on earth they were produced them like that I couldn't begin to imagine. You'll need to make sure that the D shaped regulator is matched to the generator output. I've been offered these previously, and maybe you bought yours from the same source.

If you think about it, if you have your headlights on alone, and had the measly 45 Watt bulbs usually fitted in those days, that alone would take up the whole output from the generator, never mind all of the other electrical items on the vehicle requiring power, and the need to have some power to put into the battery, if you didn't always want to be hand cranking the engine to start it.

I would investigate the possibility of changing the internals, so as to have a higher power output. Failing that, use bicycle dynamos on each of the 4 wheels to aid output!

Here is the markings on the one side of the V Reg. Im assuming the 90 means 90 watts then?
Maybe they didnt expect them to drive these cars around in the dark... 😂

Btw, sorry to sort of highjack yoir thread John...

Hi there,

I also took some pictures comparing my 1946(?) generator with a 1950 generator.

There are some differences to note when you compare mine with the other generators in this topic:
- location of the date stamping: I have another 1946 generator that came with my incomplete 46 engine (if anybody has parts for me? )
I thought its Jan. 44 but then I noticed the "B" stamping. What does the 1Z stands for?
- Can't read the the original code that was stamped in, because it was removed. If you look closely, a "RED" sign can be read. The code ends with "46", could this be a reference for the year?
- There is only a Bosch logo, no Bosch script as on the other generators here
- There is a rabbet that goes across the generator body

Just some input...
I love to see all the invisible and unimportant changings that were done in the 40's

Cheers,
Jan

Forgot the pics
There you go!

From this thread
Bosch Hella SWF SHO Blaupunkt date codes

1Z is January, 1944 but a B code is 1946

I'm not sure why your generator is stamped twice or which date code is correct.

Yes Everett, you're right!
That's a neat thing with the Bosch date coding!!!

On my other 46 generator, there are also two stampings.

My guess is that 1Z doesn't stand for the date code, but I don't know any other use of this code.
Or it was made in 44 and was rebuilt in 46? That could explain why they changed the stamping

I have a 90 watt regulator. Marked 1Y wich is 1943?!
That would fit an 90 watt generator. Must have been enough power back then?

No, I just have found this regulator two years ago.
My cars are not older than 1949.

But when there are 90w regs and gens from a certain time period, it looks like it worked. They drove those cars didn´t they?

Yes, and headlight bulbs were 35 watt, not 45 as someone above posted. Wasn't a whole lot of margin, but with a good battery it would be just fine.
