THought it was a bad alternator. It's not. Helping elderly cousin on her car. Read 12.48 V at the battery when I got there. Start the car and it reads 11.88 V. Both, at the fender terminals and at the alternator as well. Put on a new one and it read 11.84 V. Returned it and had them check the old one. It worked at the store. Reinstalled old alternator. Still at 11.88 V. So...I resume, since voltage is being controlled by the pcm, that it's a faulty pcm. She doesn't have the bucks for 190 dollar pcm. I did find an external 'kit' claiming it solves the problem. Kit runs around 70 bucks. Anyone have experience with these regulator kits for Chryslers?
