Just want to give you a heads up. It's best to keep the hood closed when you're running your compressor. Opening the hood on the 4XE shuts off charging to the 12v battery and starts the engine as a safety precaution. You can end up draining your 12v this way if you pull enough power. Instead keep your hood closed so the IDCM module maintains charge to your 12v battery since we don't have an alternator on our engines like a traditional vehicle would. All the charging is coming from the high voltage battery to the 12v so we don't want to stop that while running the compressor.

Good to know. Thanks.
