Electrical systems & I are not friends, so I have little experience with this. I don't know how to interpret these readings or how the range changes what I'm seeing. Searching has turned up lots of stuff that seems to assume that you know this. TIA for the advice.
  Both of these readings were taken with the circuit in the same state. (I thought I had one when set to the 400A range). |

Does that meter have a clamp or are you in series? Acceptable draw (rule of thumb) is anything below 0.050 miliamps. I've done parasitic draw test on my car and get 0.010 or less. I use a Fluke 88 multimeter in series. Hope this helps.
