battery charging - Do I need to fuse batteries in parallel?


I have two deep cycle batteries in my Airstream, in the panel there is a fused bus bar (that appears to be faulty) so the solar panels only charge the one battery. Can I just run a heavy gauge wire between the two positive and two negative terminals? Or do I have to put a fuse across them? ... if so do I fuse the positive or fuse the negative? What's the worst that can happen if I don’t fuse them?
