Known by cager wrenches as 'finding a ground'.  In most cars, everything 
is wired hot, and then the control switches provide a path to ground for
the other pole.  Makes the wiring simpler, but if a wire wears through
and grounds to the chassis, things go on that shouldn't be on.

This doesn't sound like Lisa's problem, though.  She blew a fuse, which
would have to be on the high side.  Sounds like the hot wire to the 
instruments could have worn through and found the ground though.  That'll 
make fuses go away.

Lisa, inspect the wiring harness around the steering head.  Anywhere you
find insulation worn away, tape it up.  The metal wire takes a long time
to wear through: it'll still be OK.  Then reroute the wire, look for sharp
metal edges, etcetcetc. to avoid recurrence.
