The stator, regulator, and battery components are dependent on each other... If one fails to perform properly, it can damage one or both of the other two...
You keep replacing the regulator, and the problem returns... that leads me to suspect you have an issue with one, or both of the other two... or the wiring/plugs between them.
As many have suggested, you need to evaluate the entire system... battery, regulator, and stator.. to ensure all three are at spec...
Let us know what you find when checking them out...
Good luck with your repair...

That happened to me. Caught it by warning light for low voltage. Which in turn would not have been charging my bike.
I am starting to see your frustration with people not getting back, so we can help them with their bike.
Sounds like stator is fine, Though I don't agree with some year manuals that say to just look at low RPMs. Maybe they figure that is where you ride, I would also rev it up. Should be around 20 volts ac per 1k rpm depending on year and model, give or take. But I suspect from my chair, it is ok.
Unless you are riding a lot, replacing twice a year is silly, and should have stopped there.
No mention, that I read about what he was seeing for DC votlage

Battery is brand new. When I test the regulator on the battery or coming out from the other side of the regulator I'm not getting any readings what so ever

Plus how often are your ridfing?
I hope you saved your parts, I got feeling they are fine. Granted i am ok replacing something froom 2008 based on age.

What do you mean not getting any readings??? If the battery is charged, will at least see that. Should see it go up to 14.4 volts dc at the battery, when revving bike up.

I'd look for broken wire or connection. Granted you are going the right way. I would have assumed same. But if you already replaced it once, something is funny. Did it read right after replacing last time? Which would eliminate idea of broken wire. Maybe ba connector that is coming loose over time? Unless you are putting on lots of miles
You are measuring voltage out of stator. But no DC at battery. So somewhere between reg and battery. Which isn't much of a clue.
That year have a plug at volt reg? Could measure DC there. Careful not short leads togehter. I would be nervous of that when stick probes in.

How many miles since last time, and what brand of regulator? When buying one last time, I thought it was cycle elelectric, but it was to cheap and worded funny. Was some knock off. If you are getting AC output, and no dc increase in voltage it sure sounds like volt reg or broken wire. I think the maxi fuse must be good if bike is running?? Would have to look at prints.
