ithe test sheet shows the alt puts out 120amps at 13.5V
PS. If the test was run at 14.5 Volts, max output would have been less than 120.
Its not major, but makes it harder to compare. 120 amps x 13.5 V = power. Then divide by 14.5 Volts to get the current and the new voltage.
Chrysler's factory specs were done at 15 Volts (see your shop manual), so the output current looks lower when compared to a test made at 13.5 Volts.
The shop manual test was also usually done at 1250 rpm, whereas the ratings are usually done at high rpm. Again making it hard to compare. Sometimes the FSM lists both, sometimes not.
