If you are speaking of the short cable with a two pole rubber plug, the exposed conductor is the negative lead and would be connected to the negative terminal of the battery. With a positive ground, the exposed conductor touching any part of the metal would be a direct short across the battery. The fuse is on the positive side on the cable so unfortunately is of no use since it never sees the current. Some solutions would be to keep the cap on as the company suggested or else put another fuse in the cable on the negative side. If you have a battery disconnect switch, placing it in the ground or positive side and turning it off when the tender cable is exposed would be another way to prevent the problem.

You are correct that the problem wouldn't happen in a negative ground car which is undoubtedly what the tender was made for.
