It will take about 24 hours for your converter to top off the batteries. After that, it should read 13VDC +/_ a little for at least 30 - 45 minutes after turning on 2 or 3 lights. You "might" have bad batteries, but maybe not. If you test with 12 VDC deep cycle batteries and it works, make sure your wiring to the batteries is connected correctly. It's pretty easy to "confuse" the black/red vs black/white and wind up blowing another converter if the fuses don't protect your new investment !!!!!
Keep us posted on what you find

ADDED: OOPS I just saw your most recent post about the batteries being fully charged, so, if they really are fully charged, then you "might" have a problem with the 6 VDC batteries. Possibly, only one of them is not holding a charge, but to find out which, you'd best put them on a load tester at an auto store. AUTOZONE will do it for free. Once you know the status of those batteries, you should be in business, either with new 6VDC or 12VDC batteries

I had them on a charger separate from the trailer to make sure they were fully charged.....now I go back to I grabbed 2 perfectly good fully charged batteries out of my mom and dads trailer tonight......12v each. Same result. AND>>>>>>the monitor is dropping with the trailer plugged into shore power??
