2. INTRODUCTION
Comprehensive 6-24V DC test kit. Find bad earths, breaks in continuity and short circuits
quickly and easily. Can even power up components on and o󰀨 the vehicle. Kit includes
exible extension cable, crocodile clip, wire probe and back-probe.
3. OPERATION
3.1. BASIC CONNECTIONS. (See Fig.1) The probe (2) is screwed directly into the
tester body (1). To increase accessibility replace the probe (2) with
the extension lead (4). The other accessories, extension probe (3), Wire probe
(5) and crocodile clip (8) can then be plugged into the socket at the other end of
the extension lead.
3.2. BASIC OPERATION. (See Fig.2) When the rocker switch (11) is moved
forwards to the single bar position the probe will be connected directly to the
RED clamp (6). When the rocker switch (11) is moved backwards to the double
bar position the probe will be connected directly to the BLACK clamp (2). The
Auxiliary ground lead (9) is connected directly to the black clamp (7).
3.3. QUICK SELF TEST. (See Fig.2) Unroll the unit’s cable. Attach the red clamp to
the positive terminal of the vehicle’s battery. Attach the black clamp to
the negative terminal of the vehicle’s battery.
3.3.1. Press and hold down the rocker switch (11) in the forward, single bar position.
The LED indicator should light RED.
3.3.2. Press and hold down the rocker switch (11) in the backwards, double bar
position. The LED indicator should light GREEN.
3.3.3. The unit is now ready to use. If the LED indicator did not light, the cause may be
that the clamp connections are poor or the unit is damaged.

3.4. POLARITY TESTING. (See Fig.3)
Contacting the tip of the probe to a positive (+) circuit will light the LED indicator RED. Contacting the tip of the probe to a negative (-)
circuit will light the LED indicator GREEN. Contacting the tip of the probe to an open circuit will be indicated by the fact that the LED
indicator is off.
3.5. CONTINUITY TESTING. (See Fig.4)
By using the probe tip together with the auxiliary ground lead, continuity can be tested on wires and components which are
disconnected from the vehicle’s electrical system.
3.5.1. When continuity is present, the LED indicator will light GREEN. NOTE: DO NOT press the power switch.
3.6. FOLLOWING AND LOCATING SHORT CIRCUITS: In most cases a short circuit causes a fuse to blow or a circuit breaker to trip
and this is the best place to begin the fault tracing process.
3.6.1. Remove the blown fuse from the fuse box. Hold the probe tip against each of the contacts in the fuse box in turn whilst moving the
power switch to the forward, single bar position. The side which causes the LED indicator to turn o󰀨 or causes the unit to sound is the
shorted circuit.
3.6.2. Note this wire’s identication code or colour. Follow the wire as far as you can along the wiring harness.
3.6.3. Locate the colour coded wire in the harness and expose it.
3.6.4. Probe through the insulation of the wire with the probe tip and move the power switch to the forward, single bar position to energise
the wire. If the LED indicator turns o󰀨 or the unit sounds you have identied the shorted wire.
3.6.5. Continue testing the wire at each connector in the harness. The wire which causes the LED indicator to turn o󰀨 or causes the unit to
sound will lead you to the shorted area. Inspect the harness for signs of chang or burnt out wiring and replace or repair as
necessary.
3.7. ACTIVATING COMPONENTS REMOVED FROM THE VEHICLES ELECTRICAL SYSTEM. (Such as fuel pumps, starter
solenoids, magnetic clutches, blower motors, cooling fans, lights etc.) See Fig.5. By using the probe tip together with
the auxiliary ground lead, components can be activated, thereby testing their function.
3.7.1. Connect the auxiliary ground lead’s clip to the negative terminal of the component to be tested. Contact the probe to the positive
terminal of the component. The LED indicator should light GREEN indicating continuity through the component.
3.7.2. Whilst keeping an eye on the green illuminated LED, quickly rock the power switch forwards to the single bar position and release it.
If the green indicator changes instantly from GREEN to RED, you may proceed with further activation.
3.7.3. If the green indicator went o󰀨 at that instant or if the unit sounds, the unit has been overloaded. This could happen for the following
reasons.
a) Where the tip of the tester has contacted is a direct ground or a negative voltage.
b) The component is short circuited.
c) The component requires a high amperage (e.g. a starter motor).
NOTE: When the unit sounds, a circuit breaker within the unit will trip. This breaker will reset automatically within 3 to 5 seconds.

3.8. POWER LEAD FEATURE (SEE FIG.6).
WARNING! Haphazardly applying voltage to certain circuits can cause damage to
a vehicles electronic components. Therefore it is strongly advised to use the correct
wiring diagram and diagnosing procedure whilst performing tests.
3.8.1. The black clamp and the auxiliary ground lead are connected through the unit. By
leaving the red clip disconnected from the vehicles battery, the unit can be used as a
long power lead.
3.8.2. Be careful to avoid short circuits and overloading when using this power lead
function. In this conguration the leads are not protected by the units circuit breaker.
3.9. ACTIVATING COMPONENTS WITH A POSITIVE(+) VOLTAGE WITHIN THE
VEHICLE’S ELECTRICAL SYSTEM (See Fig.7).
3.9.1. Contact the probe tip to the positive terminal of the component, the LED indicator
should light GREEN. Whilst keeping an eye on the green indicator, quickly rock the
power switch forwards to the single bar position and release it. If the green indicator
changes instantly from GREEN to RED, you may proceed with further activation.
3.9.2. If the green indicator went o󰀨 at that instant or if the unit sounds, the unit has been overloaded. This could happen for the following
reasons.
a) Where the tip of the tester has contacted is a direct ground or a negative voltage.
b) The component is short circuited.
c) The component requires a high amperage (e.g. a starter motor).
3.10. ACTIVATING COMPONENTS WITH A NEGATIVE(-) VOLTAGE WITHIN THE VEHICLE’S ELECTRICAL SYSTEM (See Fig.8).
3.10.1. Contact the probe tip to the negative terminal of the component, the LED indicator should light RED. Whilst keeping an eye on the red
indicator, quickly rock the power switch backwards to the double bar position and release it. If the red indicator changes instantly from
RED to GREEN, you may proceed with further activation.
3.10.2. If the red indicator went o󰀨 at that instant or if the unit sounds, the unit has been overloaded. This could happen for the following
reasons.
a) Where the tip of the tester has contacted is a direct positive voltage.
b) The component is short circuited.
c) The component requires a high amperage (e.g. a starter motor).
WARNING! With this function a vehicle’s fuse can be blown or tripped if grounding the contact is in series with it.
3.11. TESTING TRAILER LAMPS AND CONNECTIONS
3.11.1. Connect the unit to a battery of the correct voltage.
3.11.2. Attach the auxiliary ground lead to the trailer ground.
3.11.3. Probe the contacts of the towing electrical connector whilst rocking the power switch to the forward single bar position. This lets you
check the function and orientation of the trailer lights. (See Fig.9).
