Ok will do. As far as I can tell it doesn't have a fuse.

It's possible we just complicated OP into a non-functional system.

My multimeter says my batteries are at 12.3V and when I put it on the solar wires going into my charge controller it goes a little haywire ranging from 100mv to 350mv. There's still no display even when I unscrewed all connections and put them back in, so I tried hooking my panels/batteries up to my separate 30a adventurer charge controller and the display wont go on either. My mppt charge controller is made is China so I'm unsure how helpful they'll be in customer service.
What would you guys suggest I do?

Power coming in from the panels? Maybe a connector came undone.

I think the thread already discussed polarity.

Yes there's 20V and 2.7A, when I measured in my last post it wasn't on the copper part of wire but on outside cover. I double checked to make sure my solar wires aren't in reversed polarity in charge controller.

Just to update the charge controller display is now back on. I have idea what happened, but I'm not gonna push my luck. My next step is going to be purchasing the terminal connections john61CT recommended. Thank you all for your patience so far, I truly appreciate it guys.
