Hi,
Since I’ve installed my new Orion XS, the Aux Fuse of the BMV shunt blows.

Orion XS has been serialy integrated on my System. Car battery to Orion Input and input of Smart shunt. Output to CBE DS300LS.
Since it only messures Voltage, I do not understand why the fuse of Smart shunt Aux input blows.

Any help appreciated.

And you are dead certain there is no short in the cable anywhere (pinch point or small cut)

double check - no short !
