I've been sitting in traffic 2-3 hours playing music full blast (bosè system) and charging my iPhone. Is that enough to mess up the battery. The car died in traffic on 3rd attempt started back up. FYI new powerful heavy duty battery fitted 3-4 months ago.
But I noticed today for first time with this car 3-5 times while not moving in traffic the rev dial will drop suddenly towards 0 then shoot back to 1 and settle what could that mean? (P.s same day car went dead in traffic I think due to playing music full blast for 2-3 hours in traffic)
my mate suggesting alternator dying?
