Hi.

My MIL has just moved house and it has a number of outside
lights. Some are 12v and some are 240v.

A couple of circuits aren't working and the cables are buried
underground. Does anyone know of a way of finding the route
and/or checking where a cable break might be, - without digging
up the entire lawn! ??

Some people reckon that dowsing works and that most people can do it
- doesn't hurt to try (unless the neighbours start taking the ****
too severely).
