Alternator problem

I am having problems with an alternator that does not turn on the light of the chivato (or excitation) and I do not know if it is because the regulator is spoiled, or it is an alternator too new and needs another type of excitement, so I turn to you to see if someone can give me a hand please ..

This alternator only has an excitation connector:



So I think the connection should be like this:



The problem is that the excitation bulb does not turn on and the battery has a load, since if I put the bulb directly to + and - if it turns on ..

What surprises me is that the alternator is brand new and I don't know what car it is since I want it to make an invention and it gave me the same as car outside .. I bought it in Wallapop with its box and it is seen that it has not been used ..

This is the reference in case someone can serve:

Anyway, thanks in advance.

Remember to feed the alternator with dough, if the load warning ampoule does not turn on the circuit, the alternator is very simple, coarse cable current and terminal deliver or small pin of rotor with a serial blister ..

.... Some Chinese spare parts come from factory

I responded by teleserie type chapter,
I observed a detail that can be important, perhaps the ampoule is too large and will not turn hand, that is proof that current is circulating through the rotor coil, and remember that the blister could be very large for the
