Safe and simple to use, the 'BUZZ-IT' from Martindale is a real improvement for awkward sockets. It has an audible signal to tell you instantly whether or not the wiring is correct, and can also be used as a fuse finder, as the correct fuse is located when the buzzer stops.
If there is a problem the pattern of LEDs indicates the fault. Any results other than three indicators lit and a continuous buzzing tone shows a fault condition.
