    My bit of advice is to get sh775 regulator, I've had a few oem Suzuki regulators fail where they started over charging. One just recently even. Taking out the ignitor can be a big hassle and expensive.

      I ordered a used SH775 for the 850L, and it should arrive tomorrow or Tuesday.

      My road trip has been canceled, but I've had the opportunity to do a lot of the work I've been putting off on the bike so I've slowly been checking things off the list. I'm to the electrical now, and today I decided to see what charging voltage is. At idle, its 16.5V and at 3k its 17.5V. Last time I checked charging voltage, it was around 14.5V if I remember correctly. So now that it's at 17.5V, that means my R/R is not working correctly, right? Glad I went ahead and ordered an R/R.

        I installed the SH775 today on my 850L and it's now charging at 14.46V. Glad that's working as it should!

        For future reference if anyone needs an answer, the SH775 will bolt directly in the same place as the original R/R with the original fasteners, on the bottom of the battery box, on an 83 850L.

          That same spot works for the G model as well. Curiously enough, my stock reg/rec unit was next to the fuse panel, but there was no way the larger SH775 would fit there.

            Where there already threaded holes on the bottom of the battery box for yours?

                Yes. I regret not pulling the battery box and turning it over to mount it though. It was a real bear to fasten in place.

                  Cool, good to know for my 850G.

                  Funny you mention removing the battery box. Before I started working on it, I wondered if I would be able to fasten the new module in place with the battery box in the bike. After evaluating the situation, I decided it would just be easier to pull the box out. I'm glad I did because it was super easy to do, and I had to use an impact screwdriver to get the fasteners broke loose. I would have never gotten them out had I left the box in place, and i likely would have stripped the heads. Also, since the batt box was out I was able to clean off some surface rust and repaint it to help prevent it from rusting out.

                      I have had my Compu-fire for close to that long with no problems. I was worried about it recently because my battery has gone dead on me a few times. Then I realized that my MotoBatt battery is almost 9 years old when a friend told me they don't last more than two or three years on average. I guess I have gotten a lot of service out of that battery.

                        I may have owned only 6 or 7 batteries, but each has lasted more than 5 years. Considerably more.
