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). |

Ahh... Jwest or Engman?
I do know on the Engman there's been issues with the fuse block bridging. If you look at the pic, 45* left from the round relay you can see the back corner of the fuse cover popped up a bit. That all comes apart and you will find a bunch of circuits jumped with a wire. Peeps have had issues with the jumper wire and the wire is why the cover won't sit flat. |

Removed that cover and this photo is what I see. Perhaps it is something that can't be seen.  To aid my understanding, is the lower side the supply from the battery or the output? I don't understand why contacts are bridged if they have separate fuses. |
