Previously installed it, was working like a charm. Recently post a camping trip the smart shunt appears to have stopped working correctly. I use Lifepo4 battery and kings battery box. The shunt continues to show negative, even when I turn the battery box off - so there is nothing pulling energy.

I thought I was having issues with the solar charger today (it was showing 2amp below what I was reading on the regulator). But then noticed when nothing was attached I’m getting -2amp+.

Does anyone know why this may be?

Any help will

Be greatly appreciated! I haven’t been able to find this issue online. I’ve tripled checked my wiring - it’s odd because I haven’t changed anything and it was working great before a few days ago.

Your topic reads as nothing connected but pic's show negative connection at the system side of the shunt, and the smart shunt is still running.

8% battery @12.97v seems inaccurate.

Have you disconnected the system side of the shunt and done a zero/calibration?
