My daughters van's battery light came on while driving and all electrical stopped working . She pulled over shut it off and it would not start again. Got the van towed home. Her boyfriend changed the alternater and battery and still no charging. She lives in the upper pennisula of Michigan and I am trying to help her diagnose from southern Michigan. Had her charge the battery again, 12 volts. While running measure voltage at the battery and it is 12 volts and decreasing, alternator not charging. Engine off measure battery cable on alternator and have 12 volts. The alternator has a two wire connector. I am not familiar with Chrysler products but I assume one is a battery sensing and one is alternator field control. Does anyone know of or have a wiring diagram for the alternater / PCM? I would like to measure these wires and full field the alternator?
