Generator looks good and I can get it to motor but don't know where to go from here. Green book doesn't help much in that area.
 
Following up on Tippie;

The stock regulator MUST be mounted flexibly to keep out the bad vibes. 

Also be sure to route cables and other wiring around it so it can move around freely.  As soon as vibes set in, the contacts start flopping all over the place and battery charging suffers dramatically.

Alternatively, a modern solid-state regulator effectively eliminates all these problems...

If you decide to go to a Solid State Regulator for a Generator you should read these articles that points out the difference between Lucas and Bosch Generators.

http://www.aoservices.co.uk/bosch.htm

Bosch Regulators require the DF terminal on the regulator; however, you can wire the Bosch Generator like a Lucas and use a conventional regulator.

If you stick with the original 11AMP Bosch Regulator, they are fickle to vibration and getting hard to find and costs plenty. I've used a VW 30 AMP Regulator in a fix and seemed to get away with it but I've heard it's not good.

I can't see why you could not wire the generator as per Lucas and buy a cheap 10AMP Solid State Regulator.
 
It looks like my VR is pooched and I'd rather not rewire my generator. Has anyone found a suitable direct replacement or know what other vehicles these came from?
 
Other then China on Alibaba.com, anyone know where I can buy that BOSCH 9 190 040 099 E 14v Solid State Regulator in North America, Porsche Dealers may be. Wonder if Wolfgang might know? ;o)

Still think it's easier just to wire the generator as per Lucas and use a Standard Cheap 30v 10 AMP Solid State Regulator.
 
That Bosch regulator was bought at my local auto elec.
Just dug the receipt out, holy crap, I paid $180 for it 18 months ago :o. That was back when I was throwing money at my Lav like crazy.
 
I believe this is the BOSCH 9 190 040 099 E 14v Solid State Regulator for here in North America - Check out the bottom Item on this page:http://www.cpgenerator.com/voltageregulators.html ITEM# IB9028 for $36.99.

Must have the DF Terminal for a Bosch Generator

Here's some more good reading: http://wiltonae.com/articles_reviews/article_Precautions/index.aspx
 
I'm still on the bench with this one, purchased a direct replacement from Lordco for $110 and thought I had it whipped but still not charging.

After following a link posted somewhere here: http://www.netlink.net/mp/volks/htm/gen.htm

My generator will turn like a motor when wired that way following their directions. I get 32v max (which is a little under there 40v)

Inside the generator looks good, brush length is fine as well as brush tension.

However this supposed Bosh replacement says: "Warning Do Not Ground DF" and I am wondering if it really is the new voltage reg that is the problem now?

Yes I tried running a new ground back to the ground strap and I rubber mounted it.
 
Are you getting any voltage increase at all?
Are you getting amps to climb at all?
From your visual check and the tests your genny should be putting out something. That narrows it down to the regulator or a problem with your wiring. If the pilot lamp has any earthing between the globe and 61 it will not charge.
You don?t know someone with a charging 750 you could try the reg from?
