EMON II false amp reading

I’m working on an EMON II for a customer. The amp draw reads minus 5a even when there is no load as confirmed with a clip-on Fluke meter. I shorted the shunt sensing leads together and got a correct 0.0 display
I cleaned the negative cable grounds at the shunt and it worked perfectly for 4 days…0 to .1 amps displayed at no load.
Then on day five, right back to -5 amps (no load).
More bad connections or is a repair called for?
