Hi
I have installed a Victron BMV712 on my boat and the guys doing the final connections have wired two negative wires to the shunt 'battery' post. I wanted to sense check this with you if possible please? In my fancy diagram you will see that I originally planned to have the STB start batteries negative attached to the load side of the shunt...
I hope my diagram and pictures make sense. I have a house bank of AGMs that the BM is monitoring, but the 3 way switch allows me to call on the starboard starter batteries for reserve power if I ever need it.
My query is that the two bank's negative wire is on the battery side of the shunt. Is this a problem if I do not use the starter batteries? I am not worried about the BM being out of whack for the super rare time that I use STB starters in an emergency.
Thanks for your help
