H3 Alternator whine

[chaos254]

Ive had an alternator whine for awhile now that ive been meaning to figure out but just havent had the time. I have new battery terminals and that didnt make a difference. From what ive read, it sounds like it could be a ground issue or the alternator. No issues with charging or anything but its really annoying. Hopefully someone can point me in the right direction.

The only alternator whine I ever had (not the H3T) was a from a bad bearing.

Yep I'd say a bearing as well.
