2006 Great West Sprinter House Battery

[beedada]

Hi everyone, I have a 2006 Great West Sprinter Elite I bought from another forum member (and which belonged previously to yet another forum member I think.)

We renovated the interior and exterior and love it!

But I was changing the house battery and messed up on the picture I took of the connections. Now I'm not 100% sure which wires went where, even though it's just two pairs.

Would anyone know which wire goes where, on this picture? I was pretty sure the two black conduit jacketed wires go to positive and the two white wires to negative, but that is not powering anything and one of the solenoids keep clicking when connected this way.

Thanks in advance for any help!
