I've heard motorcycle electrical systems are more delicate than automobiles, and there is a chance you could've hurt it if you used a normal car charger on high boost to get it to start. I've definitely been told to never jump a bike from a running car or anything that can produce automobile charging system levels of amperage.
Your battery for sure failed, and you may have lucked out and the taillight just died from the voltage spikes. The flickering can definitely happen because of your battery.
If voltage was rock steady at 13.9 with it idling, I think your stator and regulator are ok and it's just the battery that needs to be replaced.

I go through batteries every two years no matter how much I spend on one. I did have my charging system crap out and replaced, but batteries are pretty much junk anymore. I gave up trickle charging them, I just budget for a new battery every two years, sometimes get three out of them but it isn't worth the worry... Rhino, is this on your daily drivers or cars that sit? I started just disconnecting the batteries when parking for extended periods and have gotten 7-10 years out of them. That may no longer be true though as I have heard the Battery MFr's (mistype 🙄) have been cutting costs by decreasing the internal pates etc. I was specifically talking about my 91 Softail Custom Harley-Davidson I have owned since new. I have tried every imaginable battery made for these bikes, lead acid, AGM, and whatever new technology that has come out since I bought it and still have to get a new one every couple of years. Like I said before, no matter what I do or use that is the fact, they just do not last...
The funny thing about science is that if you change one miniscule parameter you change the entire outcome to the way you want it.

Yeah the battery I took out was an AGM, my son bought when he first got this bike, which was inherited from an uncle that died of cancer, said uncle had owned since 2003. My son then rode it 2 years, but can't no more because car seats for a 2 yo and an 8 month old, don't fit on a bike. So with gas at $5/ gallon last year and my 70 mile a day commute now I have it My son had put on a battery that came from a federated auto parts store lasted about 3-1/2 years, "almost" 4 riding seasons The first one I put in was bought 10/4/22 and lasted 1 ride last fall,2 starts/warm-ups over the winter and 1 ride 2 weeks ago. Went to start it last night and it was stone dead. I did have it on a battery tender all winter, but didn't plug it back in 2 weeks ago after that 1 ride. I just got another just like it from the Interstate place this morning, guy put a tester on it and claimed 500-amd-aome CCA. Both the one I bought in October and the one I put in this morning are both AGM. I know I haven't had the luck out of interstate batteries in my cars/trucks nor do we at work, but they were the only place of many I called last fall that had one for that bike in stock. So I bought what I could get

Try "east penn battery", made in the USA. not sure if they have bike batteries. The "intimadator" for your diesel pickup trucks is a great battery.

I was amazed when my battery took a charge last month and the bike fired up! I charged it and it is holding for now, going on a long ride today, supposed to be 85 here... Jim what brand battery? I will have to look, went on a 50 mile ride today with the wife and no issues. Will check it out tomorrow and let you know...

Thought you said you were going on a long ride (85 degrees). Lol
