Alternator does not work?

[Austria_Cobra]

straing behavior

I had 2 alternators (the same), one in car worked and is now dead.

I tried the good on yesterday. Start 14,0V, loading about 25A.
After an hour of ride, the voltage goes down 13,9, then 13,8, then 13,7 and then out 12V(Batterie), also now dead.

Could someone tell me exactly what this alternator needs on the pins (SILP).
Which is an input/output, which signal should be connected (voltage)
I think the alternator is running in fail safe and kills himself after time.

2W check bulb works fine (L)
clock wise (from front) rotation
