I have a starter battery, a leisure battery, a DC/DC, MPPT and PV and Multiplus. With all functioning except DC/DC since I isolate the start battery there is a -0.02V showing on the smart shunt for the starter battery. What is this indicating?

When you isolate the starter battery, are you also isolating the voltage sense wire from the smart shunt? this should go via a small fuse directly to the starter battery. A schematic of your installation would help with a question like this....
Mike thank you for the reply. I am not. The sense goes from the shunt to a fuse at inlet of the battery positive the isolation is beyond this nearer the battery.
Isolation just removes starter battery.
