This is my first post and i tried google, youtube, Insta etc for help. My 712 was working fine and it showed the correct numbers but suddently it shows the wrong Voltage. For the starter Battery it is 0,03 and for the House it is between 0.3 and 0.4 Volt. I tried to hard reset the monitor, plugged of the cable for 20 minutes. Also the Shunt Connection has the correct Voltage. So instead of 13.6 on the house it shows 13.3 and for the starter it i 12.71 instead of 12.74
we also checked the batteries, they are in a good condition.
I hope someone can help and it is just a minor Problem.
