I'm bench testing. And powering from a completely separate battery, then through the isolators. There is no electrical connection between the power supply and the substitute battery pack. And I didn't have the voltage sensing wires hooked up at the time, so the common ground that the Link 10 and both batteries are supposed to have isn't there.

I suppose that could be the issue. But that seems weird to me. It's just reading amps by the voltage difference between one side and the other of the shunt, a dead simple thing in my mind.

I'll hook up the voltage sensing leads, and see if being "grounded" will affect it in any way. Thanks.
