Trying to figure out the capacity of my alternator

In case anyone else is interested, I learned this today:
  • 117-amp was standard on 2.5s and 4.0s through 2000, with a few rare cases of the 81-amp.
  • Starting in 2000, a 124-amp was optional, e.g. included with tow packages.
  • Starting in 2003, the 2.4s had 124- and 136-amp alternators.
