I just installed a BMV-712 Smart into a Jayco Melbourne 24L. Upon install, it is showing only Voltage readings. If I turn devices on, the voltage falls. If I turn them back off, it climbs backup. If I hook up to 120V, it shows 13.52v. However, it is not showing any amps. This stays at 0amps.
The system is connected to a Duralast 27DC and a Duralast 24MD-DL that are in parallel.
I tried a plethora of sources and videos, but still could not figure out exactly what the issue could be.
Should the second negative wire (chassis ground) of the 24MD-DL battery be connected to the shunt? or because they are in parallel, connected to the Negative of the 27DC?
If I do need the shunt on the other side... is it better to have the shunt closer to the ground? The two compartments are about 5 feet apart as a wire would travel.
