Good evening,
I have this car that occasionally when driving, the alternator light comes on for a moment and stores code P2504-21 in the engine control unit, the amplitude of the signal is below the minimum value. I have checked and the alternator charges regularly, fitting an intelligent alternator charges as needed, disconnecting the sensor on the battery charges to maximum (14.6 volts).
I would like to ask if any colleagues have already experienced a similar failure. Thank you
