I have Problems with my BMV 712 . Im Sure that i haf install everything correct, but the Monitor dosnt work.
The battery Pol of the Shunt is connected with the minus Pol and the load Site of the Shunt is connected to the System ground.
+B1 -> Battery1 +, +B2 -> Battery2 +
I send the Monitor back, but the seller says it Works. He Send another Shunt, Same Problem ...
I Switch the phone cable, still nothing.
I tyried ist with other cables for the +B1/B2, also nothing.
now i Test the „Energy Flow“.
Shunt - to Shunt +B1/B2 has no Connection, i was mit able to get the 12.8V.
Anybody and idea ? What did i wrong?
