High charging voltage - Brutale 1090rr 2010

Today, I started my brutale after two weeks and after a few minutes idling, I noticed that the battery voltage spiked to at least 17v (I have a voltage meter installed) and shortly after the bike died. I started the bike again, and it run for about 30s, showing the normal voltage which is about 14v, and the voltage spiked again and the bike died. I'm guessing I have a bad regulator, does it make sense? Could it be a different issue? A month ago I was driving and the dash started flickering, and shortly after the bike died. I had to jump start the bike, since the battery was dead, but I made it home, and no issues for the next 60 miles or so. Not sure if it could be related.

I apologize if there is already a thread covering this, but I could not find info related to high voltage at the battery. Thanks.

A true 17V would mean your reg/rectifier is dead.

If you jumped from a running car it could have damaged something. But a dead battery while riding indicates that the battery is probably not charging, due to bad regulator or bad alternator/generator.

Yep...you've killed the regulator. Do not try to ride with voltage that high or you might damage something else!!!

Thanks for the feedback. I used a portable jump starter, so that probably didn't kill it. I'll replace the regulator, hopefully that fixes the problem.
