2003 Dakota 3.9 SLT 4x4. While driving battery light comes on & engine runs till battery dies. Batt & alt checked out as good. Took to dealer & they ran electrical test & couldn't find any parasitic drains. Put full charge on batt & ran for approx 1 1/2 hrs till battery is drained. I unplugged connections on PCM & sprayed with contact cleaner & applied dialectic grease & reconnected. Drove for 2wks before battery light came on again. Is the PCM bad or is it another culprit. Thanks for any advice you could possibly send my way!!!

The voltage regulator is incorporated into the PCM on that truck but check all your wiring, fusible links and fuses first.
