Is it possible to mount a new replacement PCB to a regular Victron Shunt, not a Smart Shunt?
I found this product that does not show mounting holes for the PCB, but I assume they are on the back side of this shunt?
Shunt as displayed in this link:
Many thanks in advance!
I purchased one of those shunts, it has holes and screws on the side. I attach a drawing I downloaded from Victron. I did not attach a Victron PCB so you would need to check the hole locations are suitable.

Thank you, that is helpful. The online vendor couldn’t tell me if the holes are there, but we’ll know when the part arrives. I can’t see why you would otherwise use the shunt if it didn’t have a way of mounting a measuring device across it. But I am far from an expert I admit!
The shunt arrived and is installed. It does indeed have the mounting holes for the PCB. Waiting on the replacement PCB still.
What could cause the shunt to burn through like in the image?
Was the installation with this shunt on a yacht? Becaus this looks like galvanic corrosion to me.
If it is, you need to check all of your anodes and all ground paths/bonding straps.
Next to that check if you have a galvanic isolator or (preferably) an isolation transformer in the shore power line.
Thanks David, it is indeed on a boat. I will look into the grounding paths, bonding straps, this would be a good learning experience!
A galvanic isolator was already installed by previous owner.
I would agree with corrosion here rather than thermal damage. Another explanation is if the shunt was in a battery compartment with lead acid batteries that could have been venting acid fumes / liquid especially if the compartment was damp.
Thank you, appreciate the feedback! Replaced the shunt and PCB, but still no life in the BMV monitor screen, checked the comms and power cable as well. Next replacing the display itself.
