2000 G16 not charging

Actually, the VR works by grounding and ungrounding the green field wire at a fairly high rate to regulate the generator output voltage. Current now reverses and flows in the other direction (from what is now the generator) through the still energized solenoid contacts and charges the battery.



Hope this helps and good luck with your fix.- Ray

That does help me to understand how it works. I have a vr ordered. I'll post and let you know if it fixes the problem.
Thanks for your help.

Update. After checking everything I possible could and eliminating everything but the voltage regulator, I decided that was the problem. Got the new one put on today and sure enough that was the problem. Thanks bigstik40 for your help!

I have a G9 and s/g is putting out 17 and change new voltage regulator and still not charging the battery. I assume i have an issue with power from my r/w wire to vr. Not sure what the brown and green do. Any thoughts?
