I've got a customer who has a fairly comprehensive lighting scheme installed by a previous contractor which we maintain along with the rest of the landscape. The only problem is that we don't know where wires are buried and we don't know when something goes wrong other than checking a bulb, where else to look.

We have two sections of the system that won't turn on, so we're thinking cut wire. Are there any tools out there than can trace burried wires - or do we need to dig/pull up the old wire throughout the yard hunting a possible split in the wire?

Also - I'm looking for a good training book with a trouble shooting section for low voltage lighting. Any suggestions on a resource?
