Battery fuse wires

We have not used our travel trailer in over a year. We were preparing to take a trip but discovered no power from the battery even though it was fully charged. Our son looked at it today and discovered the plastic cover over one fuse at the battery had gotten hot and melted the rubber covering. My Dh doesn't know anything about it and said we would need to take it in to a repair shop. Just wondering if someone could give us any info that would help. We have a Jayco Whitehawk travel trailer.

    Many times the fuse holder self-destructs due to corrosion. They are not made out of the best of materials.
    I like to coat exterior electricl devices with an anti-corrosion grease. I coat the fuses prior to installing in fuse holder.
    i coat lamps prior to installing in sockets to prevent the same problem.

    He probably means Dielectric grease which is non conducting. Buy a tube online.

    Chances are a connection got loose or corroded and caused the the fuse to draw more current which made it get hot and melt. as most have said, just find a replacement fuse holder and solder it in place of the old one. also check you connections at the battery to make sure they are tight and the white wire witch attaches to the frame as a ground.
