FF310 Short Circuit Detection Tutorial

This video shows an FF310 FaultFinder being used to trace a short circuit in a 1995 Honda Civic Coupe. The FF310T (transmitter) is connected to the circuit via the (included) fuse socket connectors, and the FF310R (receiver) is used to track the wire through the interior panels, into the trunk (boot).
