From battery and lights, to starter and alternator, the electrical system of modern cars is quite complex. It continuously monitors electrical circuits to ensure every component is operating within the range intended. Any faults or variances outside the operating parameters could be logged by the system and illuminate a warning light which will display to advise the driver that something is not operating correctly. If that happens to you, you should immediately consult an auto electrician, as electrical services are very specific and can be performed only by technicians as professional, highly qualified and experienced as John Harwood.
