Common negative across two banks of different voltage?

[kflod]

Hi,This sounds weird to me, but it looks like my 54MY is wired with common negative for both the 24V and 32V bank? Could this really be the case?In the staircase down to the galley, just above my genset room, there is both a 32V and 24V switch panel. And what looks like the 24V positive main feed cable (red cable and labelled 24) is routed to the port battery bank. Previously, it was connected to the third 8V battery getting 24V, but this has caused unbalance in the battery bank. Thus, I'm now rewiring this cable to dedicated 24V bank. But, as the only cable coming down from the 24V switch panel is this main positive, my new bank has then no negative... So the question is; can I connect the negative on the 24V bank to the same negative that the 32V bank uses?I feel like an idiot asking this, but this forum helps me every time, so I hope you don't judge me too harshly

All bank grounds are common. A 32 volt neg should be on the same bus bar as the 12 and 24 volt negatives.

Thanks, Scott!
