Did you hook up the batteries backwards?
Follow battery negative cable to frame ground....check that it is clean/tight.
If you hooked up backwards.....swap cables then check the 2 large fuses on converter.they are 'reverse polarity' fuses and are probably blown also.
With 120V unplugged..check for 12V DC on converter where battery cable connects.
