Voltage readout on dash 10v-diminishing to low voltage warning. IO41 code set sometimes. Voltage taken at same time from battery and lighter is 14.5-13.5 normal

Could be an issue with the computer controlled of the alternator-its like a built-in voltage regulator that is malfunctioning-Double check
