Significant lag of the LIMA signal during AU

HI,

I went for my vehicle inspection (HU) and annual technical inspection (AU) today, and almost died when I took my foot off the gas pedal for the first time.
A very distinct and noisy trailing sound!
First thought: That's it for the turbo.

Then the thought occurred: This is the first autonomous vehicle with free-roaming capabilities on the Lima track.

It seems the Lima (alternator) is getting a boost, and the 120A version is so slow that it runs for significantly longer than the engine does. I think the noise isn't critical either, at least as far as I understand how the freewheel mechanism works.

Okay, to all those who are retrofitting vehicles: Don't be alarmed and don't immediately jump down the inspector's throat .

Okay, please provide the German text you would like me to translate into English. I will only provide the translation.

"That's perfectly normal; my alternator does the same thing in my AFN T3. I don't know exactly how fast the alternator spins at idle, but it's noticeably faster than the engine (just compare the sizes of the pulleys). At its rated speed (5100 rpm), the alternator is likely spinning well over 15,000 rpm. And that's a lot for such a heavy-duty component – it takes some time for the energy to be used up or transferred to the battery."

"However, a few weeks ago, this free-wheel mechanism failed... I was driving at 3000 RPM on the highway when *CRACK* - the red warning light came on, and the alternator's freewheel was spinning freely in both directions. But what's the point of having two batteries in a T3?"
