Dudefire, that seems very strange to me! Our FF and as far as I can remember all of the trailers we have had use the built-in Convertor to charge the batteries so there is only the one set of fuses in series with the lights, furnace, etc. I would use my voltmeter/multimeter to investigate what is happening.
