You are not alone my friend. Last week, I also dealt with the same issue on my 2020 Hd ELW. I had a coolant pump malfunction message and that sale malfunction indicator light that you had to the right of the bar and shield. Since then, the malfunction indicator lamp has gone away but I still go get some glitchy charges. For example, sometimes the charge will just stop and I have to unplug the bike and plug it back in. I actually have the bike going into Hellbender Harley-Davidson in Conyers, Ga on Friday for another concern(LCD screen starting to bubble) so I will be bringing this up as well. Perhaps a software update? Cooling pump replacement? Something else? I guess I will find out soon.
As for you @Ecanup1, I would just try pulling the plug a couple of times to get it to charge but im guessing you should bring it in for service.
