Find Any Fault In 3 Steps
STEP 1
Connect
Clip the transmitter to the circuit you want to trace. No stripping wires, no piercing insulation.
STEP 2
Trace
Run the wand along the wire and follow the tone through insulation, behind panels, along the frame rail.
STEP 3
Isolate
The tone drops out right where the break is. Open just that section and fix it.
