82 GS750 electrical oddity.. need help

[posplayr]

Update: I opened up the ground wire in the headlight socket and double checked it. It looked good. Then decided to double check the ground wire at the starter solenoid. The PO had a different looking ground wire set up than I'm used to. Moved them around some, didn't help and put it back like it was. All of a sudden it started working right. Now with the headlight connected and working, it starts every time. I'm guessing now that the solenoid ground wire was dirty and cleaning it up was the answer.




However, I did do the quick test, as you've mentioned several times. Since it was apart and running with a new battery, now was the time. It was a good thing too as it seems that my R/R is bad. When I had it running at 5K rpms, the voltage just continued to rise...14.5 ...15 ...15.5 ...16 .... 16.5... I stopped there. So I'll be looking for a new R/R now.

Thanks Posplayer for being so insistent.

I bought this bike from another person and pretty quickly gave it to one of my sons. I just got it back in time to put it up for the winter so I haven't had it long myself. It ran perfectly the whole time my son had it but now that it's back with me, I'll have some catching up to do as far as checking everything out.

Thanks everyone for your input. It's appreciated.

Guess what that ground is not just for the Solenoid to click over, it is also how all of the current in the harness (all current carried by the B/W wires) gets back to the R/R(-). You should now read "GS Charging System Health" and fix those problems and then redo the Quick test.

And if you are wondering what R/R to buy read GS Stator..........

You probably have a poor grounding system and all of your connections between the R/R and the rest of the bike are suspect. You are being offered a "free pass".....................

Ok, thanks Posplayer. I will do that. I don't mind running through the whole system and double checking everything before I just go out and buy a new R/R.
