Recently Ive heard like a humming sound and my wideband will go from 14ish to 16ish for a few seconds(at idle). All the lights on the dash will come on for a split second(very dim) I decided to check under the hood(night time by the way) and I could see a arc going from the alternator to the chasis of the car. Is this a sign of a bad alternator or something else? NO problems with the car staring and seems to be charing ok. Im getting concerned bout frying things
