For info:
Thought you all would like to see this. Negative amps!
Plugged in. Fully charged. Nothing much on except the fridge.
If I really load up the #2 side of the load center the amps will finally go positive to readings one would expect.
Everything electrical otherwise seems to be working just fine.
Liberty reps at both Chicago and Stuart both suspect a bad #2 ammeter as the probable culprit.
Weird!
