Electrical Mess

I got into the wiring panel on the outside of the bus..... Scarry!

None of the switches on the driver panel work, nothing. I removed about 100’ of useless wire, cleaning up the compartment, got out the DVOM and found zero power on the positive hub on the bottom left. Can anyone point me in the right direction as to where the other end of that main wire gets it’s per from?

Not sure why two of my pics got turned and two didn’t. The last pic is the one I’m asking about. The power lug is in the lower right corner. Turn it 1/4 turn clockwise and that’s how it actually sits.
