BMV 712 shows voltage but not current, power, consumed Ah, Time remaining - Infinite

This was working but is not now. The negative terminal of the 100 ah battery is connected to the battery only terminal of the shunt. The wire running from the load and charger terminal of the shunt is connected to the chassis ground. The red wire is connected to the positive terminal of the battery.

I am using the settings provided by Battle born for lithium batteries.

It's correctly reading the voltage but is providing no other readings.

Synchronizing it hasn't made any difference although I'm not sure what state of charge the battery has to be at to synchronize/ Full state of charge for the Battle born battery is 14.4. Does it need to reach this level to synchronize?

Unfortunately a pic will not help. The shunt is in the back of a shelf and obscured.

Hello Cortttt, is the little printed circuit board on the SHUNT still clean ?
And also the 6pin connector?

regards, Rob
