Hi amps means low charge at idle!
You want to see 12-13 turns in each coil segment of the stator windings for higher voltage output at lower rpms. The "high-current" alternators with only 6-7 turns per winding do put out the advertised amps going down the road, and they are a lot easier and cheaper to wind, but they result in dim lights at idle, and if you are running headlights, fan, etc, there's not enough voltage to make the turn signal flash.
It's an old story. I had a motor shop custom rewind a stator with smaller wire, putting 12 turns in each pole, and never had the problem anymore.
I used to scour junkyards looking for alternators with the original factory smaller gauge wire with more turns and then use them until the insulation began failing, then swap in another factory wound stator. Smaller pulley will help, too. Rotors also have different amounts of wire, also affecting the charge rate vs speed. I love 35 amp alternators.
