Burnt Wire

Let's Pretend for the sake of discussion that the plastic slider things are still in place, and except for the ground wire the steering column is electrically isolated. To operate the horn relay and that indicator light bulb only a 3 amp fuse would be needed. So to prevent future failures replace the ground wire with an inline fuse. Just big enough for the light bulb and horn relay. Somehow in the start position electricity is finding a path to ground through that steering column, a blown fuse would prevent this. Are there any wires rubbing against steering column outside under the hood.
