3. OperatiOn 3.1. hOw tO uSe the prObe (FiG.1). 3.1.1. The probe of the receiver is built of coiled steel and may be

bent as needed in order to reach wires in congested areas. depending on the circuit characteristics and sensitivity settings the probe will pick up the signal from the wire in a range of positions. However, for the best possible range the receivers probe tip (black cap) should be positioned perpendicular (at 90) to the wire being traced and either above or below it. 3.2. LOCatinG ShOrt CirCuit. 3.2.1. Connect the sender in series with the short-circuited wire, making sure one of the test leads is connected to the circuits positive

supply (or connected to the negative for vehicles with positive supply connected to the chassis). A fuse socket (in the place of a blown fuse), connector etc provides a convenient place.

3.2.2. Set the switch of the sender to Tone, the red led should light. If the red led is dim or does not light, please check battery. Set the rotary switch of the receiver to medium sensitivity position.

3.2.3. Move the probe along the wire, the receiver should give a tone. 3.2.4. Follow the wire or check it at different points, starting from the sender and moving towards the load. Audio signal (beeping sound)

indicates the integrity of the circuit. If the beeping stops it indicates that the probe has passed beyond the short circuit point. 3.2.5. If it is difficult or impossible to get the receiver to pick up any signal, adjust the rotary switch of receiver and check again. 3.2.6. The short circuit is located in the area where the audio signal stops or changes significantly. 3.3. wire traCinG. 3.3.1. Wire tracing hook up and procedures are essentially the same as for locating short circuits. The sender sees the load (light, accessory

etc) as the short circuit or connection to ground. For wire tracing, simply follow the wire with positive (beeping) audio indicators feedback on the tracer from the source load.

For step by step instructions please refer to 3.2 locating Short Circuit.

3.4. LOCatinG Open CirCuit. warninG! observe the limits and safety precautions at all times.

3.4.1. Connect the Sender in series with the open-ended wire, making sure one of the units clips is connected to the circuits positive supply or ground. A fuse socket (with fuse removed), connector etc provides a convenient place as shown in.

3.4.2. Make sure that the clips are firmly attached to their connection points, and set the switch of the Sender to Tone. In the case of having connected the unit in any place other than the fuse socket, check that the circuit fuse is installed and in working condition (not open). If necessary, replace with a new fuse of the same rating.

3.4.3. Switch Receiver on, and adjust the rotary switch for the correct sensitivity. 3.4.4. Slowly sweep the wire with the Receiver, ensuring that the probe is perpendicular and above or below the wire being traced and as

close as possible to it. 3.4.5. Follow the wire or check it at different points, starting from the Sender and moving towards the load (accessory, light etc) observing the

positioning of the probe as indicated above. Continue this procedure while the audio signal (beeping sound) indicates the integrity of the circuit. If beeping stops, it indicates that the probe has passed beyond the open, break or bad connection in the circuit.

3.4.6. double check by positioning the probe before and after the suspected place. If the open circuit point has been found, the audio indicator will show circuit integrity on one side and not the other.

3.4.7. At this point, where the audio signal stops, you have found the open circuit.

3.5. wire iDentiFiCatiOn. nOte! For connection refer to hook-up options. Wiring can be identified by following the hook up procedures for short and open circuits, depending on the particular configuration of the circuit. 3.5.1. For identifying wires with load connected, connect sender as described in section locating Short Circuit to the circuit to be identified,

then proceed to scan all suspected wiring with the receivers probe until the beeping is at its maximum. In the case of tightly packed wires (bundles, conduits etc) it may be necessary to spread these apart to facilitate the identification process of a particular wire.

3.5.2. For identifying wires without load connected. Connect sender as described in section locating open Circuit to the circuit to be identified. Proceed to scan all suspected wiring with the receivers probe until the beeping is at its maximum, in the case of tightly packed wires (bundles, conduits etc) it may be necessary to spread these apart to facilitate the identification process of a particular wire.

3.6. SpeCiaL traCinG prOCeDureS. 3.6.1. In all cases, first set the receiver at the lower sensitivity level and increase it as necessary. Proceed as indicated in the sections of this

users manual applicable to your situation. After locating probable fault area, always verify several points in the wires on both sides of the suspected fault. This procedure helps avoid confusing signal loss with actual trouble point.

3.7. wire bunDLeS anD COnDuitS. 3.7.1. Special care should be taken in the case of tracing a wire inside a bundle or conduit when there is a split. In this case it may be

possible to follow the wrong branch for a short distance and still receive a positive audio indication. 3.7.2. The probe may be picking up the signal from the other nearby branch (the one with the wire actually being traced). To avoid following

the wrong path, the branches should be swept, while maintaining the probe outside the apex area between the split as shown in fig.2. Careful attention should be paid to the beeping of the tracer unit indicator, as it provides the necessary feedback to evaluate the proximity of the wire being traced.

3.8. tO inCreaSe the piCkup ranGe when traCinG wireS. 3.8.1. When tracing or identifying wires connected to a lightly loaded circuit (low currents), pickup range is reduced significantly. A possible

solution is, after connecting the sender in series with the circuit to trace, to replace the load (light bulb, module etc) with a direct connection to ground. This allows the sender to inject a more powerful signal that is easier to detect.

3.8.2. For cases in which it is suspected the layout of the wires is the cause of a difficult pickup or weak signal, a dramatic increase of the range can be accomplished by spreading the circuit. This is achieved by means of connecting a jumper wire between the senders live wire and a ground point (fig.3) somewhere else on the vehicle. This last method should be used only as a last resort and with the receiver set to low sensitivity, as it may make pinpointing of the precise location more difficult due to the much increased range.

3.8.3. Always verify that the sender is connected in series with the circuit being tested, as this confirms a proper connection and will limit the amount of current flowing in the circuit.

3.9. CirCuitS with MuLtipLe LOaDS Or branCheS. (FiG.4) 3.9.1. When tracing circuits connected to, or powering multiple loads and/or branches, and when these circuits are active or live, the bulk of

the current injected into the circuit by the sender will be directed to the short circuited branch of the circuit. However smaller amounts of current (or stray current) will flow elsewhere making the tracing procedure confusing or even misleading.

3.9.2. The simplest and most effective way to deal with these cases is to disconnect or remove all loads from the circuit being traced (i.e remove the light bulbs in fig.4).
