Had regulator on alternator changed due to not charing, had all codes cleared which was thrown up due to this now battery light keeps coming on & reading at battery is 13.5v when I know it should be at least 14v?
The charging voltage is correct at 13.5, sounds like the alt. Has blown a diode, this will cause the light to come on to let you know some thing is not working properly in the charging circuit. I f this is the case the alt. Will have to be replaced or rebuilt. Thanks for using2CarPros
