to the component. The arcing will take place at the tip instead of the
contacts of the switch.
INTRODUCTION
The Cargo 211083 is the best professional
electrical tester for reducing diagnostic time in
6 to 24 Volt automotive electrical systems. After
a simple hook-up of the tester to the vehicle’s
battery, the automotive technician can determine
at a glance at the red/green LED indicator, if
a circuit is positive, negative or open without
reconnecting hook-up clips from one battery pole
to the other. The Cargo 211083 switch allows the
automotive technician to conduct a positive or
negative
battery current to the tip for testing the function of
electrical components without the use of jumper
wires. And yes, it is short-circuit protected. It
tests for bad ground contacts instantly without
performing voltage drop tests. It allows you to
follow and locate short circuits without wasting
precious fuses. The Cargo 211083 can also test
for continuity with the assistance of its auxiliary
ground lead. With a flip of the power switch, you
will know at a glance that your tester is
functioning without running to the battery as
you would otherwise have to do with simple test
lights. The Cargo 211083’s long cable allows
you to test along the entire length of the vehicle
without constantly searching for ground hook-ups.
Before using the tester please read the
instruction book carefully.
WARNINg
When the testers switch is depressed battery
current is conducted directly to the tip which may
cause sparks when contacting ground or certain
circuits. Therefore the tester should NOT be
used around flammables such as gasoline or its
vapors. The spark of an energized Cargo 211083
could ignite these vapors.
Use the same caution as you would when using
an arc welder.
Cargo 211083 is only for use with 6-24 Volt
systems.

ACTIvATINg COMPONeNTs OUT Of THe
veHICle’s eleCTRICAl sysTeM
By using the tip together with the auxiliary ground
lead, components can be activated, thereby
testing their function.
Connect the negative auxiliary clip to the
negative terminal of the component being tested.
Contact the probe to the positive terminal of
the component, the LED indicator should light
GREEN indicating continuity through the
component.
While keeping an eye on the green LED indicator,
quickly depress and release the power switch
forward (+). If the green indicator changed
instantly from GREEN to RED you may proceed
with further activation. If the green indicator went
off at that instant or if the circuit breaker tripped,
the Cargo 211083 has been overloaded. This
could happen for the following reasons:
• Thecontactisadirectgroundornegative
voltage.
• Thecomponentisshort-circuited.
• Thecomponentisahighamperage

JUMPeR leAD feATURe
The testers positive battery hook-up lead and
auxiliary ground lead are connected directly
through the tester. By leaving the negative h
ook-up disconnected from the vehicle’s battery,
the tester can be used as a long jumper lead.
Be careful to avoid short circuits and overloading
when using this jumper function. The leads, in
this configuration, are NOT protected by the
testers circuit breaker.
Positive current is now flowing directly through the lead and is activating the relay.
Negative hook-up clip hangs loose.

HeCkINg fOR bAD gROUND CONTACTs
Probe the suspected ground wire or contact with
the probe tip.
Observe the green LED indicator.
Depress the power switch forward then release.
If the LED indicator changed from GREEN to
RED, this is not a true ground.
If the circuit breaker tripped, this circuit is more
than likely a direct ground. Keep in mind that high
current components such as starter motors will
also trip the circuit breaker.
fOllOWINg AND lOCATINg sHORT
CIRCUITs
In most cases a short circuit will appear by a fuse
or a fusible link blowing or a protection device
tripping (i.e., a circuit breaker). Here is the best
place to begin the search.
Remove the blown fuse from the fuse box. Use
the testers tip to energize each of both contacts
in the fuse box. The side which trips the tester
circuit breaker is the shorted circuit. Take note of
this wire’s identification code or color. Follow the
wire as far as you can along the wiring harness,
for instance if you are following a short in the
brake light circuit you may know that the
wire must pass though the wiring harness at
the door sill. Locate the color-coded wire in
the harness and expose it. Probe through the
insulation of the wire with the tester tip and
depress the power switch forward to energize the
wire. If the tester circuit breaker tripped you have
verified the shorted wire.
Cut the wire and energize each end with the
tester tip. The wire which trips the tester circuit
breaker again will lead you to the shorted area.
Follow the wire in the shorted direction and
repeat this process until the short is located.

UsINg THe lIgHT AND TONe
The Cargo 211083 has the option of a light and
tone. Once connected to a good battery, the light
and the tone will be activated.
The light illuminates the area you are testing and
is a great asset for seeing in dark areas.
The tone feature enhances the polarity signal.
When the tip is contacted to a positive circuit,
a high pitch tone will sound off. When the tip is
contacted to a negative circuit, a low pitch tone
will sound off. The tone can be toggled on or off
by pressing the audio tone On/Off button.
