Tracing wires downstream (from supply to load): replacing the load for a full short indicated above. Continue this procedure while the audio signal (beeping sound) and circuit allows the FF300 to work at its maximum capabilities. Before proceeding visual signal (flashing green LED light) indicates the integrity of the circuit. If beeping... -

Electromagnetic loop size and geometry, etc. may affect the range of the 8 - Tracing Wires inside bundles and conduits FF300’s. For example for circuits in which the live and ground (return) wire run parallel and close to each other in the same circuit. The two magnetic fields Careful attention should be paid to the beeping and flashing speed of the tracer unit interaction may weaken the signal, thereby reducing the FF300 range. -

This is achieved by means of connecting a jumper wire between the live wire (preferably 14 - Technical specifications at a termination point in the circuit such as a light bulb socket or a switch, etc.), and a ground point somewhere else in the vehicle ( see Fig. 9).

Page 8: Care Of The Unit
15 - Care of the Unit The FaultFinder is a precision instrument and should be treated as such. Damage caused by mistreatment is not covered by the warranty. Keep the units in their carrying case when not in use and do not subject to dampness or severe heat or cold. - Page 9 Part # FF300M9909EN © 1999 General Technologies Corp. Printed in Canada...
