Replace the fuse with a stoplight bulb or better yet a 65-watt
headlight bulb, then use a sewing needle and your voltmeter on 200 mv
range to follow the voltage around the circuits.  The circuit where
the voltage is decreasing as you go along is your baby, and when it
drops to zero you've just passed the short circuit.  Keep sniffing
for smoke while you're doing this, that can be a clue as well - but
the bulb will keep the current within what the circuit is supposed to
be able to handle.
