I went and checked the voltage of the batteries (2 deep cycle new batteries).. They read 6.35 volts. I unplugged the 110 power and they still read 6.35 volts. i did this several times and it seems the voltage doesn't change wether they are plugged in or not?
Again, checked fuses/breakers and all good.
I checked the outlet that the converter plugs in, 118volts.
I checked the power leaving the converter and it was 6.35 volts (same as power at the batteries).
It sounds like you have two 6v batteries wired incorrectly (parallel)
If you truly have 12v batteries then the two batteries should be reading 12v each not 6.35. Take a picture of your battery wiring and then disconnect all the wires off the batteries. Wait a few minutes and take voltage readings again.
If you have 12v batteries (6 cells per battery for adding water) and reading 6v then your batteries are dead.
If you have 6v batteries (3 cells for adding water) then your batteries are wired up incorrectly.
Check this diagram carefully against your batteries taking note of the number if cells per battery. Then wire your batteries accordingly.

Once your batteries are wired correctly you can check the voltage from the converter. But it's entirely possible that you did blow some fuses.
