10 years ago I installed a post lamp in the front of my property.Â* The
house builder left a 2" plastic conduit (maybe 100 feet) from the house
to the area where the post light was to be installed.Â* I put a 4"
square
plastic box at each end of the conduit as ground level.Â* The house end
is no problem as it is in the asphalt driveway.Â* At the house end, I
connected an underground "romex" to a breaker on the panel.Â* At the
other end, I connected 2 underground "romex", one to the post light and
one to an outlet, some 25' away.Â* Through the years, the outside box
has
disappeared and I can't find it.Â* I've tried raking up the leaf mulch.
Nope.Â* I've also tried one of the non touch voltage testers.Â* Nope.
I've tried a tracing unit connecting a signal to the power line and
snooping with the other end.Â* Nope!Â*Â* I don't have a metal detector.
Not sure where to go from here.Â* Any great ideas out there?

Two possible ways to find the box/wire. Easier way first.
Â*Â*Take a portable AM radio, tune into a station, hold the antenna so
the back of the radio faces the ground. Rotate the radio around
keeping the back facing the ground. You should find a direction where
the signal drops very low or disappears completely. Now keeping the
radio in that direction, lower it to the ground and pass it over the
area where you think the wire is. When you pass it over the wire the
signal level will pop up. (The wire in the ground re-radiates the AM
radio signal and causes it to locally come from a different direction,
thus the radio picks it up) Once you find the wire, just work your way
to the box, sliding the radio back and forth listening for the signal
to come and go.

I like that one. I will have to try it some time.

Bob F, I did too, but it didn't work for me, but the AM radio did work.
Check out my posts from yesterday.
