Hi. Just noticed this problem...

When my 99 Accord v6 EX coupe is idling....it is making this wining sound. I opened the hood and it seems to be coming from the alternator area...it's kinda a lound wining type sound...is this the alternator going bad? Seems to be from that area or is something else? When I'm accelerating, i don't here it...only when i'm idling...my vehicle has just over 100k on it and its an automatic.
