I have a Redarc BCDC1225 connected to my starter & Aux batteries, with a red Anderson plug installed on the front bullbard, connected to the yellow wire on the bcdc. The BMV712 & shunt are installed in the back of the wagon, with the Aux battery wire connected to the battery side of the shunt, and the fuse block for my lights, USB, ciggie sockets wired back to the load side of the shunt. Everything works as it should for this, and I can monitor everything properly through the BMV when the accessories are drawing power.
Also connected to the load side is the starter battery, and the BCDC charger earth.
I have just gotten my solar panels, and hooked them up today through the red Anderson plug, and whilst the voltages of the batteries increased, I could not see any current in the BMV, it just showed 0. I had the solar connected and used something i know draws roughly 9 amps, and it showed a draw of -4A on the BMV, which means that at 1700, the panels were only putting in 5A, which would be about right. I disconnected the solar, and it went up to -9A, showing that there was solar input.
How do i get the correct reading on the BMV for this? Do i need to connect the Anderson plug negative to the shunt aswell?
thanks for any help!
