Question:

this power control center is o my Montana 2016 5th wheel. I changed the two batteries and after the DC run items in the camper do not run, everything when on the AC when plugged to AC runs fine. Have I blown something up in thecontrol center and is there a switch in the unit check?

I reached out to my contact at Progressive Dynamics who makes the # PD4575K18LS8 you have installed in your Montana 5th wheel trailer and there is a few different things you will need to check to find what is causing your DC trailer outlets to not have power with the new batteries.

First things first check that there are no blown fuses in the fuse board that could have blown due to hooking the batteries up wrong or hitting the positive terminal against the trailer frame.

If the fuses check out fine then you will want to check that there were no wires/connectors going to the battery that did not get hooked back up when you installed the new batteries.

Check these things and let me know what you find. If needed we can go into more in-depth troubleshooting steps.

I included a video of the # PD4575K18LS8 for you to take a look at.
