Q: Car shuts off, battery light on after part replacement - 1992 Mercedes-Benz 300SE

asked by on

A week ago, I was driving the car when the dashboard started showing the battery light illuminted. The following day I was driving again and the car just shut off. I immediately had the battery replaced with a new one and everything was fine for the next two days. After that the battery light started flickering and the car shut off yet again. As I wasn't able to restart the car, I bought another battery and had the previous, also new battery, replaced. The car started after that. Just before the engine starts running, I've noticed that the electrical components in the car start losing power. The lights become dimmer, the radio turns off etc. What might be the cause of this issue?
