Orion working but not showing as charging on my shunt display despite my MPPT shows as charging both negatives run before the shunt
Hi @Sampeett
The Orion GND can go to the Load side of the shunt, and the batteries should also be linked together there as well. If you have a chassis ground link, make sure that follows this requirement, and doesn't bypass the shunt.
Should the ground from the Orion go to the shunt? Before you ask the shunt is not backwards as in the daytime the shunt displays that it is receiving + and it also flashes.
When I start the engine the Orion displays 14.3 for the vehicle battery and 14.5 for the leisure batteries. However the shunt display shows -14.5v and does not flash.
