2015 charging issue

I have a 2015 flrtx and tonight when i was pulling my bike into the garage i noticed that my battery light was on my bike only showed 12v on the gauge. I shut the bike off and then just turned the ignition to the on position and it showed 12 volts. I then started the bike and it still only showed 12v. I think that its not charging the battery when its running. I didnt really have much time to mess around with it but was hoping someone could point me in the right direction to checking out the charging system and where i can find the voltage regulator and other things to check to trouble shoot the issue. The owners manual says to check for a bad grounding strap connection. Where can i find that? The bike is completely stock and only has 5xx miles on it. I am planning on riding to laconia on Saturday and i hope to find a loose wire or something easy. I also plugged it into a battery tender to charge the battery overnight. I hope i can find the issue tomorrow or it looks like no laconia for me this year... thanks guys!

Take it to the dealer for warranty work; probably the voltage regulator. The VR is a common defect, quality problem with Harley's.

+1 on the Voltage Regulator, it could also be the stator too, but taking it in to the dealer as mentioned would be the right thing to do since the bike is under warranty.
I wouldn't ride the bike to the dealer if the dealer is too far away because once the battery goes dead the bike will shut down and you will be stuck on the side of the road waiting on a tow truck.

i called my dealer and told them that i was planning to leave tomorrow to go to laconia and he told me that if i could get the bike to them that he would make sure that i would make my trip. So i loaded it into the back of my truck and headed to the dealer. It ended up being a loose connection on the volatage regulator. I was happy that they could get me right in and take care of me. So it looks like im NH bound tomorrow!

Glad to hear the problem was resolved. I'm still trying to chase my charging problem. I'm stuck with trying to figure out where the ground wire from the battery is anchored to the engine or frame. Anyone have a picture of can give me the location? I'm figuring to clean all connections first and see if that resolves the 11 volt at 3000rpm problem...probably not but what the heck, that process is fairly free and easy.

Thanks in advance.
