My battery on my GR650 started to struggle and I was wondering what could be the cause? After some research in this forum, in the manual and some measuring I finally figured it out. It was a bad r/r. 12.5V@5000 rpm and wrong resistance and more. I almost immediately order a new regulator (shunt type) from the EBay, but I just had to check what you guys do in this situation? I didn?t know about the Shunt VS Series r/r and SH775. But thanks to you and your experience a learned that don?t go for a another Shunt type of r/r. Go for a SH775. I ordered a used SH775 from EBay and install it. Now everything is working perfect. I?m measuring 14.6V@5000. :-)
I?m celebrating this with a beer. Wishing you all a good evening and thanks once again for this magnificent forum. Never stop sharing your knowledge

Sincerely
