Not getting power from new RV battery :(
Hello Everyone, I am trying to do a little problem solving. We are not getting any power from our new RV battery. We have check the leads, fuses, wires (looking for loose ones), converter, and bat...

You get 12V DC when on shore power so converter is working BUT you do not get 12V DC when not on shore power
That mens you have battery disconnect switch OFF (if you have one) OR you connected new battery cables up backwards and blew the fuses on converter.
Converter has 1 or 2 large (30A or bigger---depending on converter) 'Reverse Polarity' fuse(s). They blow when battery is connected wrong to protect DC system/circuits.
They are on backside (or side) of converter.
Check cables on battery. Don't assume colors mean anything!
Follow negative cable to trailer frame----ground
If cable on battery negative does NOT go to trailer frame.....correct cables and replace 'Reverse Polarity' Fuses
Also New battery will not charge if they are blown
