The current delivered by a source is a function of the voltage of that source and the effective resistance of the load. In this case, the load is the battery and the source is the alternator, of course. So if you have the voltage but not the current, the "load's" resistance is too high. (This actually happens to batteries as they age).

With 14.3 votls, I'd think the current available is fine - EXCEPT for this excessive AC voltage you mention!
I suspect a bad alternator and no, I don't think parts are easy to find for these.
