Our house has a buried cable that was laid by the previous owner for a
potential lamp in the yard. It is hooked to a switch in the house,
but there is nothing on the other end. Is there a way for an
electrician to find it without digging?

I've used a small battery powered radio
switched to the AM band to trace live
wires before. Tune it to a relatively
quiet section of the band and wave it
near a known live wire and listen to
the humming sound it makes. I have also
used a tone generator of the type used
for tracing telephone and network cables
in conjunction with an AM radio to trace
hidden wires. The toner produces enough
RF harmonics in the AM band that tracing
a wire is no problem. You would have to
make sure there was no power on the circuit
first before hooking up a toner.
