Default New primary battery...”Brake”, “ABS”, “Stability control" lights?

Prior to replacing the battery I occasionally get the Brake warning lights. I replaced the primary battery, fully charged it and I’m still getting all the above warning lights. (Randomly)
Before I make a dealer’s day, is there something I can check?? Brake fluid is fine.
At only 19, 600 miles surely the brake pads can’t be worn out, and if so, do they give a warning??
I know I’m way behind on mileage so hopefully someone can enlighten me on a simple fix??

Could be a corroded earth point causing the random errors, there's one in the right front wheel well that some people have found problematic. What year is your car?

No, I didn’t realize it was missing so I updated.

I’ve looked in the R. Front wheel well (Wheel removed) and can’t see anything resembling a ground connection.. Can you give me a hint as to the ground connection whereabouts??

My car at 42K miles has just started doing this, it flashes a warning for the stability control, ABS, the center console screen goes out (as in black) until I start the car next and the window auto memory gets lost. It happens so fast that the first few times it happened I couldn't even read what the command center warning were flashing. This being a bad ground makes sense to me because it has happened while driving under almost ideal conditions recently.

Having a ground in the well well does not make any sense (although I guess we've seen stranger things). However under the hood just forward of the shock towers are what look like a series of grounds on both front wheels. A photo of what appear to me to be the passenger side ground connections is supplied below. I know Phillipintexas and I would both greatly appreciate it if someone could confirm.

Hey Phillipintexas, have you gotten any resolution to this problem? Mine seems to only occur when the interior fan is on, whether it is the because I have the AC/defrost or simply vent fan. I was driving the other night with the AC on, I got the "ABS, Stability Control warning..." everything blacks out on the interior briefly and the headlights flicker. This would not be a good situation if it didn't self correct quickly. Even so, it would definitely concern other oncoming drivers due to the headlights flickering (and rightfully so). My car is due in for its 5 years service interval and we'll see if JLR can sort this out.
