That's the challenge. Often there is a hint that regulator and dynamo must be compatible.

But I think you're in Germany, if so it seems unlikely that you will be able to find that particular talent.

I'd found one for my MG but he was out of talent and a little bit fraudy.

I have manuals for MM and MG - but both show different voltage values for some tests. E.g. 15.9 to 16.5 for MM and 15.6 to 16.2 V at 30°C for MG.

Because it is a range it will be approach - but knowing the particular values for the existing box would give a better feeling.

That's what I've done before but I will repeat that step for sure.
