Switched alternators growl sound difference

Post by KEOWEEsteve »

On 2006 gl1800. With the oem alternator there was a low rpm growl. Bought aftermarket and the growl went away. In the mean time I ordered honda bearings and had the oem rebuilt. After 10k miles the aftermarket started making a noise like bad bearing in alternator not the low rpm growl. Put the rebuilt oem back on and the growl is back. Thoughts? Note. The resistance to spin the alternator is a great deal greater on oem vs aftermarket

Hugh FYI ... aftermarket alternators can cause the bearing to fail at the back of the rear case. The bearing is the one seen when the alternator is removed. Also, most aftermarket alternators don't live long.

As for you OEM one. Can you make a video of the sound, post it on YouTube, and copy and paste the link here. Be aware, that if you cannot hear the noise in the video, neither will anyone else.
