Background Noise, 89 VN Calais

[Bitters]

Hi,

I have an 89 VN Calais, which is obvious from the thread title, recently i've been getting this really annoying humming type sound that comes from the engine bay while i drive it, the faster i go, the louder it gets, and its really startin to bug me. And i can't figure out what it is, Any help would be appreciated

Alternator.... That lil black thing on it, start car. open bonnet, stick head near it, turn the throttle an listen see if it gets louder.

Cheers
