would you mind if i ask the model of your alternator?

again, as i have stated several times... every mopar alternator i look up from the 2005 year had an internal voltage regulator. 1 battery wire. a two plug connector. the wires are "field control" and "sense"

field control, when ign + applied causes output to happen. field sense detects voltage and internally adjusts the output voltage on the battery wire to keep from overchargeing.

on the new cars they have a PCM that basically turns the alt off if the battery temperature gets high. it's not a voltage regulator but it drops the "field control wire" voltage to shut down charging so the battery doesnt overheat. the sense wire also goes to the PCM but really that sense could go anywhere on your car where there is a constant +

all of the sites and documentation i have checked do not list the newer hemi alternators has having a FLD / FLD as the two wires. the are FC and S

if you post the model of the alternator maybe we can find exact information

Make sure the case of the alternator is metal to metal with the front cover. I just took mine to my alternator guy to disassemble and blast so I could powder coat the case and he said to grind it back off where it mates with the front cover. That goes for the front cover too. He also said the regulator my car came with would be totally fine to use with it.
