Hello, I went ahead and checked the fusible link wire and it is in tact after inspection. What would be my next step in diagnostics? Thanks

All my wires should be okay it’s an Arizona vehicle stored in a garage. Can you tell me where that links to so I can check it? And if that all checks out what would be next step? Adding external voltage to the RD/VL wire

So asuming since that RD/VL wire are indeed to have voltage going to them could I load the RD/VL wire with voltage from an external source in order to see if the alternator then activates? or is there any other diasgnostics i can do to pinpoint if my issue is in the PCM internally, all other signs point to that. Battery is okay and alternator is okay as well. Thanks

I’ve done all of these already alternator and battery are in stable condition. As previously listed the alternator does not charge but per the linked forum both wires on the connector should be reading 12v. However the red/violet wire does not. I need to figure out any further diagnosing to confirm it’s a faulty PCM or what that listed wire does go to. Thank you.

Hello, I've got a 2016 Dodge Journey with a 2.4L with only 95k miles. As of currently I have a battery light on when I turn the car on and its in a power saving mode. I've already replaced both the alternator and battery with no luck on improvements. I found in a forum to test the wires on the connector and if none of them are at 12v that the pcm could be faulty. I tested the voltage on the red/violet wire which showed about .02V does anyone know how I can further diagnose this issue or what that red/violet wire goes to? I will link the forum below.
