Alternators are rated in amperes, not watts.

If this weren't a Chinese tractor forum, I might let that go. But the Chinese - while inconsistent - more often than not rate their alternators in watts. Here's the one you and I have for example: https://affordabletractorsalesco.com/cart/sub_catalog_gallery.php?cid=1119&catid=&picid=1281&category=&sub_category=&scid=

And I incorrectly wrote that the standard 200 series alternator is 150w, sorry. It's 200W as you can see here: https://affordabletractorsalesco.com/cart/sub_catalog_gallery.php?cid=1118&catid=&picid=1280&category=&sub_category=&scid=

If you're familiar with Ohm's Law however, it shouldn't matter. 14v into 200w means that first one is roughly a 14A alternator. The second one is 25A
