So I just bought å new stator and regulator for my 929. There is three yellow wires. 2 Green and two red connected. But I also have a Black wire that i dont know where to connect. Does anybody know if I need this one anywhere? Thanks

Hi , I know the 954 has this configuration on the Rec/Reg , the Black from the Rec/Reg feeds the Fuel Cut Off and Engine stop relay via the Black/White wire ,but the 929 doesn't have the same configuration (no Black wire) and a different wiring diagram, so it appears its a live feed, have you tried it without the Black wire connected, or maybe get them to swap it for the 929 version

Hi, thanks for answering me. Perhaps I got the 954version. I bought the regulator new from Germany. So I will try to ask them. I started the engine after finishing change it. Now i got 18,8 voltage. Its overcharging. Maby its bad grounding . I had to travel for work for 14 days so I can't check. Just have to wait to i get back home. Could you think og any reason why the voltage is so high?

Wouldn't leave that 954 R/R on though , your battery isn't going to live very long at that voltage, check the system out including the Earth, check it alongside this
Thank you for the file you attached. I will check it when I come back to my home and bike. 👍🙂

The Black Wire in the R/R is a switched live ,so I dont think thats your problem
Resurrecting this as I have a similar question.
My OEM RR burned out last year so I changed it to an aftermarket item, from what I thought was a reputable shop. It was expensive enough, but it gave up recently.
I have now gotten a genuine Shindengen SH847, which is rumored to be an excellent regulator. My only issue is this black wire with white tracer in the 954 loom connector.

From the wiring diagram, I can see that it is powered through the engine stop relay and goes to injectors, sensors, control valves, fan, fuel system etc. That seems to fit with it being a switched 12V connection. I'm guessing that it doesn't need to be connected to the Rectifier/regulator then, is that right?

Just to close the matter, as the info may be of use to someone.

I left the black wire in the loom's regulator connector unconnected and tested the bike just now. It starts and runs without any problems. The regulator maintains a steady charging voltage of 14.6V, from idle up to 8000 RPM. I didn't want to go higher, I'm testing in my driveway, it's getting late and I want to stay friendly with the neighbors :). The regulator didn't get noticeably warmer in those few minutes of runtime. Now I just have to find a spot for it since it's larger than OEM.

That will be OK, the Black (Black/White) wire is a switched Sense wire to the Rec/Reg to Switch off the charge to prevent Battery overcharging, you can see it spliced into the loom
