Hello if I start the car the warning lights going automatic on. Anyone know how to fix it ? Thank you https://youtube.com/shorts/a-GK9_sCUNw?si=BYlDIhQGJec4RACs
It's going to be your alternator then, voltage regulator, normally they go high voltage not low, but anything is possible. Is that 9 volts at the battery ????, there's nothing to say that your new battery is good, get it checked just to rule that out.
