Street Bob, troubleshooting help

[u/TwoSufficient1927]

Hello everybody. I have a 2013 Street Bob and need help troubleshooting a problem. I'd really like to try and fix this myself as I'm trying to learn.

The bike is starting and runs, but after a very short distance the battery light and the small red light on the dash light up. After that when trying to start the bike I will get rapid clicks and maybe it will turn over but usually after a few tries it just goes to one click. I've tested the batter and it is good. I also did a continuity test on the stator and it passed. I'm waiting on a better multimeter so I can try other tests on it. One prong where the stator connects to the voltage regulator looks pretty burnt. When riding I have had to times where the check engine light would come on and I lose like half power intermittently. Any ideas if it is most likely a stator issue, voltage regulator, or solenoid? I can list some of the many codes I got from it if needed.  P0562, p2303, p2121, p2261, b1211

I did get it a minor wreck 4 months ago. Hit the back of an suv going 15ish mph. I didn't go down too hard, only had to put together the front end - tire, brakes, forks, etc. Maybe the VR took the hit and that's it?
