I wish I had seen your video 5 days ago, I just went to the shop someone else did it for my YJ Jeep. I got rid of code 46 but I still have code 41, "Alternator field control circuit open or shorted".

If you have a external volage controller. The main pcm will not have a field connected to the ult so i might be seeing the circuit is disconnected since the aftermarket one is connected and not it
