Exciting Alternator without Battery: Marelli 63377002, D+ & B+ Outputs, Connecting to Receiver

Hello!
I have some fears to unravel.
I have such an alternator, most likely Marelli 63377002

The back has two outputs, probably D + and B +

Well, I have such a question for more experienced people, whether by directly connecting to a current receiver after accelerating this alternator will the current flow on the receiver?
I know that there is a 5W bulb between D + and B +, but then people have an alternator connected to the battery.
There are self-excited alternators of the 9 LEDs, but as it protrudes from this second screw to connect it probably will not be my alternator? (comes from cars ~ 2004). So far I have no way to check it out, I will be able to do it after the weekend. Possibly, I would ask for some ideas on how to get electricity from it to the receiver, what to raise it. Thank you in advance for your help!!

The alternator has a built-in voltage regulator that controls the excitation.
If it does not exist, it means that it is an ordinary generator.
The battery should be to relieve the alternator slightly and stabilize the voltage.

Generally, all alternators installed in Volkswagen were self-excited, so that they "surprised" it was necessary to exceed about three thousand revolutions on the engine. However, working without a battery is not recommended. The regulator may have problems with voltage stabilization. In the toddler, with the B + wire broken, the voltage could exceed 50 volts.
B + is a battery connection terminal, D + is awake.
Excitation is enough to give for a moment, then he will manage himself.

Will giving an excitation for a while through a small 12v accumulator pass the exam?
The direct receiver occurs in order to permanently load the alternator

In the case of a battery charge it will work, at least in what I checked, it always worked, in the situation of another receiver it is difficult for me to say. The voltage can be given by a 3 to 5 watts control, there will be a control of the operation.

First of all, you can burn diodes in this way, secondly there is no such thing as a self-excited alternator.

Your reasoning is wrong in its entirety.

Most of today's are not self-aware, certainly not on the F00M regulators, most of the valeo and magneton. They need voltage for good morning because the controller is a PROCESSOR.

After the second topic, it is straight into the basket.

OK, I checked the alternator is 6 LEDs.

But only a part can start charging without external excitation in the range acceptable to them, the VW Group starts at around 3 thousand engine revolutions, that is probably with 4.5 thousand of the same alternator, and Fiat can be turned into sections of the engine and nothing. Speech of alternators from the plus or minus range 1995 to 2005.

I have heard that there are self-excited alternators in which vehicles operating in difficult conditions are equipped. Mainly they were assembled in various vehicles, including "civil" ones in the former Soviet Union. A part of such an alternator will be made in the form of a "dynamo" and rectifier, which is used to excite the second part, ie a traditional alternator.

I know that the subject is old but I have to write my opinion on this matter because I know Fiat alternators from a toddler to those used today; first of all, "if it's a Fiat Alternator M. Marelli, e.g. AA 125r-14V ... it's obviously that it will wake up itself and doesn't even need high revs ... it just starts charging normally from about 1000 revs. Secondly, nothing will not happen if the excitation terminal or current terminal with load is not connected, because all ELECTRONIC controllers have a built-in voltage limiter, someone wrote that in a toddler voltage in this way jumped to 50 V .....- it could have been but if it was the regulator was not original or the original electronic one was damaged, otherwise it could not be so.
