I just returned from about 25 miles. All seems well, voltage going up and down dependent on rpm, just as it should. The V11 power never grows old. After riding my other bikes(V7, GL500, ZG1000) the last couple of months while this was being worked on, this V11 seems like a beast, so much more fun to twist the throttle. I breached the ton a few times today!

yes @docc, this is the case. However, I was going to disconnect the red/green altogether as I've now run a direct wire from the positive battery to the RR. However, when I did this, no electricity at the key. So I expect the red/green powers something else essential. I did look at the schematic, but my eyes went goofy navigating the lines and colors.

Yes, I swapped to a CB, per Docc. As for less vs more resistance. Less is now what the OEM line has due to the added resistance the new line. Make sense? the OEM red/green wire also powers …fuel relay?

Well it's working, but maybe only a band-aid, not actually corrected. @Tomchri I ran a direct wire from the RR to the battery, took it for a ride and it now has higher voltage at higher rpm, as it should. Thank you. (The RR I bought came with a long power wire just for this reason, but wanting to keep it OEM, I had originally chose not to use it.) The problem now is this all started when my 30a fuse started to melt at the base (not blowing). I replaced it with a CB, but that hasn't helped other than allowing me to push the button rather than replacing a melted fuse. As it is now I'm concerned that there is still a short in that main harness. A friend tells me the additional wire will help add resistance and may in effect make up for the fault. To truly repair this, I believe I'll need to remove the tank and replace this power line. For now, I'll see how this fares.

Tomchri Thanks for the reminder, let me reconsider this.

The AC results are correct, reaching 80v. (I was stupid enough)

I've tested the bike at numerous rpm, always charging about 13.4 regardless.

It's been some time since I've visited the forum. Frankly, I needed time for my moral to recover after too many attempts to repair my V11 charging problem. After replacing the battery, rectifier, and stator, it still doesn't charge above 13.4. Is there a special rectifier if I'm using a lithium battery?

I so very much appreciate all of your suggestions. Thank you. I will try all of them and report back. I'm a bit delayed trying to finish a bit of work on my KLX250, near completed.

Thanks @Weegie, I'll reference your numbers and do this again. 15 V AC @ 1k RPM 40 V AC @ 3k RPM 80 V AC @ 6k RPM

Hmmm, so I didn't consider changing the rotor. I did clean it a bit, before reassembling the new stator, looked good. I did fully change the battery (lithium), and it's been sitting on the bench for three days, let me go measure now… 13.43.

the stator is the alternator. https://www.electrosport.com/collections/street-motorcycles-moto-guzzi-2003-v11-sport

Admin: starting a new thread, merge if needed. I was stranded on the freeway this past weekend, dead battery. The system is doing the same as it has been for some time, in spite of all new items. It began over a year ago by melting the 30a fuse holder. I replaced it with a circuit breaker per forum suggestions, and it breaks often. Regardless of rpm, just over 13v is all that happens. I guess there is a harness drain/short/problem. Although I have inspected it numerous times, I will begin again. Thoughts, suggestions?

Aside from theft, in particular my KLX250 would benefit from an airtag. If I were to get lost, broken-down, etc, it might prove invaluable.
