6 volt generator - question on electrical connections

[Zylinderkopf]

OK - the electrical stuff always stumps me.

This is a 1966 Bug with a 6 volt system. I'm replacing the generator and the voltage regulator.

I'm not sure how to connect the rebuilt generator I bought online. It has a different set of wires coming out of it than the old one.

The old generator had a copper wire on one side and two wires on the other ( see picture below). The copper was attached to the F terminal on the regulator. The other two were both connected to the + terminal.

The rebuilt 6v has just one red and one black wire. I would think one goes to the + terminal on the regulator, and one to F. But which goes where??!

Here are my regulators: old (bottom) and new (top - a rebuilt Bosch)

Anyone out there with expertise in this? Searches on this topic have not gotten me anywhere. How do I connect my new generator?

Thanks

The Bentley mentioned that new generator:

And while VW said not to put the new generator with an old regulator, Bosch would say that later regulator would work back quite a ways - this chart is from 1971:

Can you tell which wire is going to one of the brush holders? That would be D+

It's very likely the red wire for D+, and black for DF. But I'd try to verify that the red wire does go to a brush holder.

If your problem is only to recognize the D+ and the DF wires from rebuilt generator, consider that D+ terminal is connected to the internal field winding and to ONE OF THE GENERATOR BRUSHES, so following the wires (removing the pulley can help) you can choose the D+; it also will be thicker.

The DF, instead, is connected only to the other end of the field.

thank you for your responses. I went with red + and black F
It took me all day to replace the generator and the regulator. Got it all put back together. Unfortunately the gen light is still on. I'm thinking 12 volt conversion at this point!

So sticking with herbie1200 as well as the original picture, in order to polarized the generator one would have to ground the DF wire on the left and touch both the D+ (One of the generator brushes) and the other field winding wire (the winding on the right) to something hot?

I too found the 0 101 212 001 (aug 1960-Dec 1963) two generator wire very hard to find. Most 6 volt replacements will be later 0 101 212 003 and 004s which are three wire generators.

I think the earlier ones must have been wired D+ and other internal field winding inside or internal. Later not wired inside (went external) for a few years. My guess, have not stripped both down to see.

It only takes a few min. to polarize if you haven't already done so.Disconnect the gen. from the volt.reg.(red & black).Take the belt off.One jumper wire on black grounded to the generator.I connect to the bolt on the gen. strap. The other jumper to battery positive terminal. Touch this one to red wire and gen. should spin clockwise..."one thousand one , one thousand two " disconnect . Reconnect everything and retry. If this doesn't work I would at least try the original v.regulator.
