The only complete Chrysler alternator curve I've ever seen is the one Nacho found in a box.

It shows the remanufacturer ran the test at 13.2 Volts.
But we can't compare that directly with the factory test for that alternator.
Almost always the shop manual test is done at 15 Volts, 1250 rpm (engine).
To compare, we need to know the pulley ratio, and then we can guestimate the performance curves at other voltages.
I just dotted in the 15 Volts without actually doing the math to illustrate the concept.
