Chris :
One way to look for shorts is to temporarily wire a load of some sort in
place of the fuse (an old dual filament headlamp bulb with one filament
burnt out with makes a good one) and then use a cheap hand compass (the
kind with a magnetic needle that points North) to follow the circuit.
When the compass gets close to a wire that is carrying current (ie
between the fuse block and whereever the short is), it will deflect from
North.
Also, the horns are supposed to be on a fuse by themselves. If they are
rusty inside, or mis-adjusted, they can draw considerably more current
than normal.
