Hello,
As I currently have my engine on a stand, running well, I thought it would be good to test that the dynamo an voltage regulator does a good job.
D+ from the dynamo, does that go to the "+" on the underside of the regulator, and DF on the dynamo to the other connection underside the regulator?
...and then 61 and 51 on the regulator to the battery?

hmmm
I think I am wrong about these connections.
If somebody have the time, could they check where D+ and DF from the Dynamo go on the voltage regulator?

Please take a picture of the underside of the voltage regulator and post it here.

Hi,
Picture attached.
One of the connectors has a "+" mark, the other seems to be unmarked.
As I understand it 51 is the output from the regulator, and 61 is for the charging light.
So my bet, as of now is
Dynamo "D+" -> VR "+"
Dynamo "DF" -> VR unmarked on underside

Your bet is right. Make sure all ground connections exist and the other wire from the charging lamp is connected to ignition+ (15)
Is it a Bosch regulator?

Great, thank you!
It is a Marelli regulator
IŽll try to hook it up in a day or two and see if I can get some charging.

Others parts of the project got in the way, and I have not made this work yet.
I suspect the regulator is faulty, but in order to rule out the dynamo- how much voltage should the dynamo itself make, without the regulator attached?

. Measured about 60mV between the two connectors on the dynamo, at idle, and about 250mV at 3000rpm

Over the years I have tried to find to find someone somewhere in Europe who can repair the OE Aurelia Marelli voltage regulators without success.
So these days, if I have a problem I fit a modern sold state regulator inside the original Marelli casing which has been well described by Tim Heath in the UK LMC magazine and also on this Forum I recall.
The dynamos themselves rarely need more than new bearings and brushes.

That's very useful Chris, thank you, can you let me know which edition Tim's update appeared in?
