  Specs for that radar show the max power consumption as 25 watts, which is a pretty small load. I've never turned my generator on for the radar.

  Your dual motors, isn't one of the alternator a dummy or not hooked up?

  @rasbury, No, both produce power and charge the batteries

  It’s the power steering pump on the port that is doing nothing typically.

  I knew it was something....two alternator must produce a lot of energy that is perhaps not harnessed? Not sure how all that works.

  Each alternator has a sense wire connected to the batteries. As the battery voltage increases (or decreases) the alternators will reduce (or increase) the charge voltage to maintain the batteries at approximately 14.2 VDC
