My battery lamp in the gauge cluster turns on after the car have been running for approx 2-3 minutes.

I have measured the voltage and when I start the engine and when it's running for the first 2-3 minutes the voltage is 14.79V, but then suddenly it drops to 13.48V and the battery light indicator goes on.

Does anyone know what can be wrong?

  • Have you done all the other charging system checks for that make and model? The workshop manual will detail them. – Solar Mike Jul 21 at 7:10
