OK a 3800 question but not a Bonneville one
But humor me
I am getting a 'buzzing' sound from the alternator upon startup of the engine. Almost sounds like the groaning of a power steering pump from the inside of the car.
The alternator only does it when cold. After about a half mile of driving the noise stops and runs without noise. It varies with RPM. It'* been charging fine and continues to charge fine....
I thought it might be a bearing but doesn't a bearing squeek? Strange indeed....
Am I going to be *.O.L. on the side of the road soon?
