IMPORTANT TIP:
When powering-up components, you can increase the life of your
Cargo 211083 switch, if you first press the switch, then contact the tip
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.
