2001 dodge dakota sport electrical problem
2001 Dakota sport quad cab 4.7L V8. The battery and the alternator are both brand new. I took the truck to the shop to have the electrical system tested and all cables were good and the voltage regulator is working. The problem is that the alternator is not charging the battery and the truck is not running on the amount of volts it is supposed to be I was wondering if I replaced the alternator pigtails would that solve the problem. Any suggestions would be appreciated.

That's not too far from normal if read at idle. My dash gauge falls almost to the red line at idle but goes to "normal" around 1700 RPM. I know idling in gear I only show 11.8 volts.

My dash gauge does that also but instead of going up it will drop down and the check gauges light comes on.

How did they test the voltage regulator? If the output is low, and you've got a code then there is a likely problem with it.
These code are from the 2001 factory service manual. Why they differ from what Magnethead posted I don't know. They're close though.
P0622: An open or shorted condition detected in the generator field control circuit.
P1682: Charging system output voltage low.
Unfortunately, the regulator is built into the PCM.
Start with the basics. Make sure all connections are clean and tight. Then, post back with what you are getting at 2000 rpm. Use a digital meter at the battery, not the one in the dash. It should be between 13.6-14.2.
