Multiplus will not run from battery

Hey, I have the multiplus 24/3000 and it is currently connected to shore and everything runs great. It tells me my batteries are full charged, and when I cut the power from shore, I don't get any. power from anything.


When I test voltage on my batteries, I get good readings, along with all my connections in the system. My problem seems to be when I connect the negative lead to the multiplus, my voltage then drops from 25V to 2V.


This is 3 straight nights of trying to diagnose, and I'm at a loss. Please if someone can help it would be great. Thank you.
