ST1300: What are the signs of a failing alternator?

[Hueyf4i]

@Jim Van bought and installed a much cheaper new made-in-China alternator in his ST1100. He reported no problems with it after 15,000 miles. Maybe he can provide an update.

Jim was was given a link to the vendor by @kiltman. Maybe he can provide it again. Maybe that same company makes a much cheaper alternator for the ST1300 as well.

I meant cheaper cost of the OEM unit. At least I know I'll get 116,000 or more miles out of a new OEM.
