Hello!
As I'm rebuilding myself the generator of my R25/3 (stator coils), I'd like to know how to wire the coils, in which place should I plug...(everything was unplugged at start !!).
I'm also wondering how the regulator works and which role has the resistance (thin wire rolled over a ceramic).
The stator coils are serial wired, one wire starting from the carbon brush plus and the other one ending ???? where?!
I suppose the regulator is offering a minus to this ending wire when the battery is under 6V but I'm not sure...
Is somebody has a wiring plan to help me?
Thanks in advance and long life to vintage BMW's .

Hallo,
you have a resistance wired over ceramic??
Normally the resistance was wired together with 1 stator coil.
the role of the R. was to reduce the incoming power for the stator coils whem the engine turns in middle range revs (about 2-3000 Upm).
The other end: DF, going to the regulator.
he is offering minus in 3 stages:
full ground: when engine low revs
ground less resistance: middle revs
short circuit : at high revs
all this in change (? Wechsel) between the points (short circuit[no power] to ground less resistance to short circuit and so on)
greetings

There is some fine electrical diagrams on the following place :
