As I understand it, if the alternator idiot light is burnt out, the alternator will not get excited and hence not work because the filament acts as hot wire to the alternator (the "exciting" part of its function).
Maybe I've crossed into old timer territory, because could this be true only in the days when generators were ubiquitous, but not in these modern times? I don't have a charging problem, but I do breathe a sigh of relief when the idiot light glows upon starting the motor.
